I remember when my aunt said to me when I was about 12, "Oh you're so tactless!" and I was mortally offended. Not because I thought it was a bad thing to be tactless necessarily but because I'd actually said what I said QUITE ON PURPOSE, and I was chagrined to have my witty and astute observation mistaken for sheer blundering social spazzness because it wasn't what she expected to hear!
I'm less mean than I used to be by a long way, I've mellowed a lot. But a similar process happens still, nowadays. Though much less often.
