OK, this is maybe the sweetest e-mail I've received yet.
You came into Trader Joe's in Lake Oswego one night and I rang up your purchase. We had a conversation about I don't remember what, and before you left, you shook my hand. I was so impressed. Your lady friend came back to get something she forgot. I had overheard her say something about a celebration and I inquired. She mentioned your book and invited me to the signing at Powell's. I loved crashers, read it in two days. Please keep writing. And thanks for being a good guy, too.
