Who's being selfish?

Selfish. There are times that I get frustrated with people and think they are being unfair to me. I'm not being treated like the other people in the group, and I feel like I need to assert my rights. I need to speak up and tell them how unfairly they are treating me and how selfish they are.

And the funny thing is, that over time I've realized that it is in these moments that I am the one being selfish. I'm expecting things that have never been promised. I'm seeing how others are treated and wondering why am I not getting that treatment; I'm missing that I get certain advantages or other treatment that is unique to my situation. I am the one wanting this person's life to be all about me. Guess who is selfish now.
