"Oh, you're so talented! I wish I could knit!"
Then get to work, because I have many talents but this is not one of them. This is skill that was woven from stubbornness and spite, tied together with tears and lots of cussing. Stitches cast on with fear and bound off with rage.
I know what the intention of the words is. I feel, though, that complimenting talent instead of skill unconsciously programs us to think, "I can't do that thing because I wasn't lucky enough to be able to do it perfectly within 5 mins of seeing someone else do it. That other person is lucky that it's easy for them."
