Toxic Friends! 10 Types of Friends to Avoid 

Also the friend who always asks for favors but only helps you when there is something in it for them or helps you once and then uses it has a way of manipulating you to do more favors for them. Some friends only do you favors so they can ask for unlimited favors . A real friend doesn't pre meditate a favor or keep score . If a mate who you have done plenty of favors for asks you for a favor and gets mad when you say no then they are not your mate ( they see you as a lesser person that they use and the whole friendship revolves around you doing them favors ) Some people see other people only as people who can do something for them and get mad when told no because they think its insulting for a person they think is beneath them to dare say no to them because in there mind they are superior to you in every way even though they would never say yes to there rude insane request if you asked them.

Great it helps
