My uncle and his son, my cousin, were both total snowflakes over Christmas.
Apparently my uncle had lent some money to my cousin, and texted him, on Christmas Day, to ask him about setting up a payment plan to repay the money (because that's always a good time to ask about things like that, right?). My cousin bean dipped him about paying the money back, and then made a strange comment about "and anyway, I'm going to see MY family today". My uncle texted back and said, "what do you mean?", and it came out that cousin believes that our family as a whole likes him and considers him more of a family member than we do my uncle.
So there's my cousin's Special Snowflake moment; who thinks it's okay to tell your father that nobody in the family likes him or thinks he's part of the family? Then my uncle turned into a Special Snowflake, and asked my mom, who was hosting everyone for Christmas dinner, to uninvite my cousin. She caved, and uninvited my cousin, and my uncle still decided to not come and pout about how no one likes him.
I love my uncle and my cousin, but my goodness...we almost had a blizzard Christmas morning! And because they're both being "Special", neither of them gave any consideration to how it would affect everyone else. I didn't get to see either of them while I was home, which makes me very sad. Of course, after the whole drama, I might have tried to knock some sense into them if I had seen them...
