A little young? Oh don't say that, don't even think it, she's going to have a panic attack about it when she turns 20 and she really tries to avoid thinking that whenever possible. Just don't talk about it. Ever.

"Oh! I didn't notice!" She lets go of the girl she is now bffs with for the night. "It doesn't! Special occasion- he got a promotion! A big one. A real big important one! So we're celebrating!" Celebrate with her, Caroline!
