I remember a couple of years ago, I was on a bus and there's an old lady sitting next to me. We had a chat, then she said that she owned a "useless old computer called Apple 2." She really wanted to get rid of it in exchange of small amount of money.

I said, "Cool, let me see what I can do, here's my email."

I was an idiot, really. I forgot that she might not know how to use email, and I didn't ask her contact.
