Oh, Esspee, other people do notice! I squirmed with embarrassment when a rather glam boss of mine sat next to me, because she had a very long, dark hair dangling from a mole high up on her cheek which grew a little longer every day (she was blonde!). I was young then and didn't want to be the one to tell her, but was so relieved when it was gone one day - it had nearly reached her chin by then
She had two teenage daughters - how did they miss it?!
I've now got a very well-used set of tweezers and the pink spring thing from Amazon (Epistick, well worth £1.05 of anyone's money).
I have noticed that the couple of white hairs that sprout on my chin are much thicker and wirier than the dark ones. I'm hoping this bodes well for when my baby-fine hair goes grey or white.
