     You wake up in the morning, the day is beautiful and the

plans for the day are what you have been looking forward to for

a long time. Then the telephone rings, you say hello, and the

drama starts. The person on the other end has a depressing

tone in his voice as he starts to tell you how terrible his

morning is and that there is nothing to look forward to. You are

still in a wonderful mood? Impossible!

     Communicating with negative people can wash out your

happiness. It may not change what you think, but

communicating long enough with them will make you feel

depressed for a moment or a long time.

     Life brings ups and downs, but some people are stuck in

the wrong idea that life has no happiness to offer. They only

feel glad when they make others feel bad. No wonder they can

hardly win others' pity or respect.

     When you communicate with positive people, your spirit

stays happy and therefore more positive things are attracted.

When the dagger(匕首)of a negative person is put in you,you

feel the heavy feeling that all in all,brings you down.

   Sometimes we have no choice but to communicate with

negative people. This could be a co-worker,or a relative. In this

case,say what needs to be said as little as possible. Sometimes

it feels good to let out your anger back to the negative person,

but all this does is to lower you to that same negative level and

they won't feel ashamed of themselves about that.

   Negativity often affects happiness without even being

realized. The negative words of another at the start of the day

can cling to(附着) you throughout the rest of your day,which

makes you feel bad and steals your happiness. Life is too short

to feel negative. Stay positive and avoid negativity as much as

possible.
