Think before you speak

Sometimes I feel really bad for people who don't think before they say anything. Its like anything that comes out of there mouth comes out because they feel bad and want you to feel the way they do. Or it's just that they suck and don't know how to say the right thing. It really upsets me because I feel like no one should have to explain to you that what you are saying is rude or not right at the time. But i guess I can live with everyone not being me or even human thinking before the speak
