a) Thank you!
b) No no, thank you!
c) No problemo.
d) It’s a’ight.
e) De nada.
f) You’re welcome.
I’m “Gen X” and the last I had to train myself to say. A and B are STUPID RITUALS I thought I had to follow when I was young and I gladly abandoned them for “no problemo” and the like.
You’re welcome came with some pain but I can do that now too.
You’re welcome was always a passive-aggressive phrase to me. I don’t know why, so I don’t like using it but I will if I think I should.
