I worked with a nurse who had very nice, tasteful acrylic nails. It was against hospital policy, but it wasn't really enforced.
Anyway, one change of shift, she and I were standing in the hallway, talking and she drew up some med, "flicked" it with her fingernail and the fingernail went FLYING down the hall!!!
WAY too funny.
I have unpleasant nails, too. My mother had truly HORRIBLE ones, that never grew out to her fingertip and were peely and curled up and just nasteeeeee, so I'm lucky that mine aren't worst. But I don't like to spend time/money, so I just keep them trimmed short. Cheap, easy, quick (heh heh - that's me!)
