      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 (令人沮丧的) tone in his voice as he starts to tell you how terrible his

morning is and that there is nothing to look forward to.Are you 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 have 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 coworker,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.
