Don't be afraid of scammers

My mother-in-law posted a classified ad for an old computer on a local website, and someone tried to scam her. I told her to play along. The scammer mailed us a check, and I even spoke to him over the phone -- eventually, I grew bored of the charade and ended it. Maybe he'll think twice next time.
