opposite of love should not be hate,
but should be forgotten;
why some people love becomes hate,
it can not be forgotten,
it is because he loves the inside,
lack of confidence ......

; in love, we need to complete two important psychological tasks:
First, to better understand themselves. In addition to the concept of self-awareness
addition,
make love in their own gender more complete clearly presented.
Second, cultivate our capacity to love.
habits from a young age learn to love being loved.

second heart is concerned. Care means caring,
which all girls are easy to understand.
third heart is empathy.
What is empathy? Is to put yourself in others shoes capabilities.
empathy is a source of respect,
between lovers is the most important conflict resolution skills.
there are two views. The first is the sincere intention
. Faith means faith, sincere and is responsible for the foundation.
second intention is good, is to be able to use good way to interpret the behavior of couples.
This is a lot of people get along with the couple is difficult to do,
such as they do not care late, with a malicious interpretation of how to make sense,
; will begin to blame each other, you do not care about me!
see a man is not a good man with three benchmarks:
responsibility, respect and stability.
charge means that he can be responsible for his own remark.
respect refers to, he will respect their other half,
is what we usually say, between you and him is the > you get along the way are equal.
In addition, he also is an emotionally stable person. easy to some emotional ups and downs
,
such people is very difficult to maintain a long-term relationship.


say is that good men above the benchmark.
conditions and then if we raise as fine a man, then,
also can sum up the so-called
first heart is happy first.
he should be a pleasant person,
this will make people get along with him feel happy.
love to be found regularly in fact,
follow these psychological and emotional needs if,
when the last time that I love you to each other when,
We will not matter.
the success of a relationship,
not see if still in hand,
but by the emotional quality of the set,
hand often does not mean successful,Dior sunglasses,
break does not mean failure.
key is to look at this relationship if you complete two important tasks in love.
you a better understanding of their needs,mac make up brushes,
you have learned to love others.

bought a stop loss of stock,
can not save it like a marriage,
should not be thrown just as if the He was troubled by the divorce should be the same.
spent on things out in all of the costs, such as time-consuming, money, etc.,
when these costs can not be recycled, in the psychological cost of being a silent.
why we do not want to leave an unhealthy marriage,
Why not give up a worthless stock,
because we do not want to admit these silent costs can no longer recall.

boys in love in the emotional needs are the following:
one's own ability to be sure. He often concerned about whether people think much of?
Second, the talent is appreciated. Perhaps some of his hobbies and talents to their work completely quit, but you still need to learn to love and respect.
Third, efforts are appreciated. His feelings for you and the efforts of this needs to be appreciated.

girls in love in the emotional needs:
one, have often been care. Although the daily nagging, please be patient and listen.
Second, again and again been affirmed. She may be three or two and again ask if you love her.
fact, she just needed again and again for certain, you need to give her confidence.
Third, ideas are respected. (When the increase in the sharing of mutual emotional feelings of many)
way to keep love everlasting:
to develop a three-by three-preservation program.
first three minutes three times a day.
three A plan, first Attention, concentration.
in our daily life, I always think the best gift we can give someone is time,
let go of all the activities you do, turn off the phone talking intently listen to each other .
second Affection, My Sweetie.
non-verbal communication, that is, body language communication. Nothing more than hug each other.
third Appreciation, appreciate each other.
each mature female body has a very naive girl,
a naive little girl every body has a naive little question mark.
that I have not liked in the end.
at this time you need to learn to compliment each other,
of course, praised each other looks,Mulberry bags, she is a good choice.
or her ability to care for the family not be ignored.

of course, a mature male of each body has a very naive young boy,
naive boy each have a ridiculous body a small question mark,
that I have not let people look down?
matter into more mature men, this little question mark remains.
he certainly learned to never love anything more than touching.
life if we think there are some incomplete parts,
is probably not done the homework.

这是高一数学第一章的东西，你的题干可能打错了！！！如果我没看错的话应该是已知a={1，3，5，7}，b={1，4，7}，c={2，5，7，8}。anb={1，3，5，7，}n{1，4，7，}={1，7}；anb={1，3，5，7，}u{1，4，7}={1，3，4，5，7}。根据此规定,可求的(a u c)n b={?}？？？
如果我所说题干正确那么（a u c) n b={1,2,3,...
