How do you give critics to a person?

For me, it all depends on who it is and if the timing is right. I try not hurt anyone's feelings. I try to give constructive criticism only. I only tell someone something fi they ask me to. It doesn't happen very often though because alot of people do not want you to say anything negativbe to them but they are the first to tell you everything negative about yourself and they never think twice about it after saying it either.

what's good for us might not be good for others. what's best for us might not be best for them. but when i see that the person is doing self-destructing attitude, i make a suggestion first. if the person asks why, then i begin giving him/her the pros and cons. sometimes it's hard because there is this thinking that we don't want to hurt their ego but then again and most often we end up hurting them when all we ever wanted was the best for them --- and yet like what i said, "what's best for us, might not be the best for them."
