Late

"Wow, you were up late."

It made me giggle a little bit that you noticed.

But, uh, thanks for noticing. Seriously, I'm sure you didn't mean for it to make me giggle but it did. It was nice in a random way that I am sure you didn't intend, but it was nice that you notice things like that. Then again, I'm weird for noticing someone noticing that. Hmm. Now go try to figure that out.
