I was thinking about this the other day... I am GOOD at folding paper, I know how to do it really professionally, to get a really flat seam... OK so not an earth-shattering skill, (lol tho I have others that are :P) but it's surprising... and it's because when i was a kid my mum worked for a printer and she would sometimes bring home magistrates newsletters and publications to finish off at home.. and I would help her.. we used to have this special tool made from bone... I also am a gardener extraordinaire and I know a ton of stuff about children with additional support needs...
And what I thought was.... we are probably all full of strange, quirky skills that we somehow acquired along the way...
It's kinda cool.... and that's one of the things I love about people... they are endlessly fascinating and have diverse backgrounds and history.
