[He offers her a small smile when she wanders up before his brows furrow slightly at the envelope. He takes it, setting his beer down to look it over before raising confused indigoes to her.]
Birthday? [He's baffled, but then it hits him, both Dean and Aidan were planning something... Could this be? Hadn't Dean thought to... SIGH. Those guys, guh.]
I don't technically have a birthday, I mean I don't know when I was born but... [Guess he does now! Carefully opening that envelope while he's talking, he wants to see what's inside. Well this is a pretty nifty idea actually. It's useful! He can actually enjoy it too. Another small smile.]
Thanks. [Gonna go ahead and pocket that so he doesn't lose it.]
Dunno, is seventeen a big thing? I've never had anyone celebrate me getting a year older.
