"Thank You"s Astray

So, I made up thank you notes, for my birthday present? And some got hand-delivered, and some got mailed?

Yeah, thus far, none of the mailed ones have arrived. I know I put stamps on 'em — "Forever" stamps — so I have no idea what happened to them.

But, let this be as much of a substitute as it can be: Thank you.

Edit: Okay, phew, some of them have arrived! I no longer fail at gratitude!
