I'm strong?

Today at work I was in an all-day class about conflict resolution. Exciting stuff. One of the segments involved arm-wrestling someone else. Yeah, really. I was partnered with Denise, a woman a few years older than me who looks pretty fit, or at least thin. I wondered if she knew how to arm-wrestle because it was so easy for me to pin her arm down. When we finished, she said "Amy, you're really strong! Do you lift weights?" This is the first time anyone has ever called me strong so I had to preen about it here. For the record, I do light weight-lifting but I have no delusions about my upper body strength. Still, I'm going to avoid arm-wrestling anyone else who might burst my bubble.
