I kinda said similar thing once, when visiting a new in law's hse(not mine, a cousin's) when i noticed a painting on a wall in their hse n offhandedly remarked it looked like a sunday painter did it(it means like an amateur or sth).
My cousin said it was painted by her mother in law n i just abt crawled away if it wasnt my cousin staying there. Luckily she wasnt there but her son heard me, i think. I tried to laugh it off or sth. But i nvr forgot even tho i might put my foot in my mouth rptdly after tat, not with them luckily. I nvr learned from tat to think b4 speaking or correlate stuff when voicing out my words.
I hvnt hopefully said/wrote embarrassing stuff online, tho idk for sure. But i try to keep wat i write to a minimum mostly, maybe to avoid doing so.
