Before you assume, try this crazy thing.

ASK!

Someone is ignoring you? Perhaps they are going to through a tough time, and don't even know they are ignoring you. Why not ask?

People aren't good to you? Maybe they are trying to be good to themselves as well. Why not ask?

Asking is the best thing to do, before making assumptions. 

It Either validates your assumptions or you get to understand people better. Either way, you get to be a better communicator.
