When I was a kid and my mum was bathing me, I was terrified of floating hair in the water. So I already had long hair at the time. I remember curling up as far as I could from these long, threatening, floating and offensive threats. My word was “thread”, as in “there is a thread”. My mother had to remove the floating “thread(s)” from the water.
Now I don’t curl up so much, but I’m still really bugged by the occasional strand(s) of detached hair. A lot.
I don’t mind attached hair at all. How funny to make the distinction.
