Somethings when you've gone too far,there's no way to return. Some people are just oblivious to their surroundings,only caring for themselves. True friends wouldn behave like this at all. Yes in life there are time where you do not like wht your friend do. But you do not get angry and do all sorts of things behind them . Instead you spend your time and talk to the person. If he/she doesn listen,let it be. Isnt seeing your friend being happy the most important? Remember,You control noone's life. So before you make decisions, Think of how others may feel. Your words may be out of anger,but some words that are said can no longer be taken back. And this words may break one's heart and then the situation will therefore become something undesirable. If this is really wht you want, go ahead. I've nothing else to say,but seriously, spare a thought for others. You've emotions,so do others.
