"don't share nail clippers. very harmful. a lot of bacteria and germs. your nails can rot and drop off if you share nail clippers".
righttt. how do you react to such helpful advice? with a "oooo-really?-yesss ah" expression of course. but its much harder to do, cause the "wth"-look would be painted really deep into your face to change it.
and as random as that advice was, i have just realized this post is also very random. it's ok, got a picture. (no words to say, so maybe picture will help :P)
