I'm used to not being invited to things. It's a shitty side effect of not having kids. Most of the time it doesn't hurt my feelings.
My niece's fourth birthday is next week. Apparently she had a birthday party today. I found out about it when I saw party pictures on Facebook. We weren't invited.
I don't even know what to think. We have a present for her and everything. Unfortunate oversight or not, my feelings are really hurt.
