"What are you doing?" Robin asked last night when he called. And thus my dilemma was born.
Do I tell him? Do I fess up? I mean, I'm an honest person but do I really want to tell my friend, "Well, I'm in my bedroom watching old *NSYNC music videos on my laptop to see if I can still do all the dance moves to Bye Bye Bye and I'm pretty surprised at how much I've retained in the decade since learning it"?
I decided to go with the boring but less deeply embarrassing, "Oh. Uh, nothing."
