Dramatis Personae: Facebook, Me, and Random Dude of Earl

So this random guy friends me on Facebook, and at first I thought it was Tashina's gay ex-boyfriend, who she's still friends with, so I went ahead and friended him back, when I notice that it says he's dating a girl in his profile.

"Hm!" thinks I, "That's odd. Who is this masked man?"

A letter appears in my inbox from him.

"Hey, are you Chris's sister?"

"Yeah," I send back. "I'm sorry, I'm awful with names, have we met?"

I just got this back:

"I'm sorry, I confused you with somebody else.

No, we haven't met, but I don't want your brother to get mad at me. He is a pretty cool guy plus he is my uppclassman, my junior in the Corps, I'm his sophomore.

Nice meeting you, but I have to erase you as my friend. I apologize for that."

I'm torn between amusement, frustration, and HOW THE HELL DOES CHRIS STILL REGULATE WHO CAN AND CAN'T TALK TO ME WHEN I DON'T EVEN SEE HIM BUT THRICE A YEAR.

But definitely edging towards frustrated amusement, in the end.
