“When the character of a man is not clear to you, look at his friends.” Japanese Proverb
Sometimes people can fool you into making you think they are different to what they really are. I find that if you are not sure what to make of someone, you can easily form an opinion based on their choice of friends. I find that family also says alot about a person. But you know the saying, you can choose your friends but not your family. So personally between both their friends and family, you can easily asses a persons true character!
