Rhett & Scarlett
[No more anonymous, since the pastries were received well, and it wasn't as creepy as he thought it might be]
Dearest Rhett,
You're more than welcome. I'm glad you liked them. I don't want or need anything in return. I enjoyed our conversation, and you seemed like you deserved something nice.
My name is Ragnar. In real life. You don't have to give me your name in return, I'm not trying to trade.
