karma does exist !!!

hello friends i just want to tell you, karma does exist please be careful with someone feel and be careful with you've done with someone, if you make one heart broken in a way that hurts and you don't care about his/her feel maybe someday you can get it back with you or we can say it "karma" , so don't be proud of all you got and don't be proud to have made one's heart sick ! ,think first before doing something !
