I'm not a nurse, but I got a funny story for you.
Let me tell you something about my co-worker sitting next to me in my office. When he gets his hair cut, I see about 10 hairs are much longer than the rest. It looks funny! Should I tell him that????
Take into your own hands.
I think you should just walk over to him with some scissors and cut the longer hairs. Get him when he is in the middle of something. He might not even notice. Let me know how it goes
