Who to trust

Noobs you must notice who you are trusting:

Brothers: Good you know someone and he's your brother he is awesome or the worst bully but fortunately for me he is awesome.
Friends: Here is how to notice if your friends are trust worthy
1. Do they ignore you when you talk to them even if they are in their little group or do they take a break and spend a time to talk to you or even include you to the group
2. Do you only see them when they are in need of help or do you see them all the time and no matter what idiotic thing you have planned they will follow it to the end
3. No matter how stupid your actions and reactions are do they still say they'll stay for some more time or will they leave on the first stupid remark you say
4. When you feel that you're mentally unstable do they even try to help? or worsen your condition on purpose
