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 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.
