Distance yourself from the vain .
Vanity is one of the deadly sins (or maybe not, come to think of it). Vain people are shallow and greedy, always thinking that looks are more important than deeds (Stupid is as stupid does). Stay clear of them – they’re never satisfied.
There are people who are so “in love” with themselves, they are incapable of loving anyone else. Stay away from them. They can wreck your life, often permanently. Have nothing to do with such people.
