Lighthearted subject, What innocent sayings really grate on you? Mine is "grown ass/arse".
My sil says it all the time and it is like nails down a blackboard everytime I hear it! I don't know why. It's usually said after unsolicited advice from mil etc. She will say "I'm a grown arse woman, I don't need her to tell me how to....." or "he is a grown arse man he should....." (usually said about her ex)
I've noticed it pop up on a few threads recently too. It is obviously not affecting my life in anyway, I just cringe when I hear it! So it got me thinking, what saying annoy you?
