I only have one friend that I'd let use one of my machines. Hers was in the shop and I told her she could take one of my featherweights until hers was ready. She turned 3 shades of pale and flatly refused. She said she was afraid it would break. I told her that really wasn't very likely, but if it did, I could fix it. She finally took one of my clones and was a nervous wreck the whole time she had it. I know she would treat mine like it was her own. She is truly the only person I wouldn't hesitate to send any of my machines home with--even my really good ones!
