Let's suppose you say a university professor or an elder person who you think a great deal of them, something not pleasant. Suddenly you see that they get upset. Then which one of the following sentences would be a a polite sentence of apology to tell them:
- I didn't mean to take the liberty.
- I didn't mean to act rudely.
I think the first sentence works better than the latter one and the second one sounds a bit too formal in colloquial, polite language. If no one of my sentences work, I would really appreciate it if you do me a favor and let me know what do natives say rather than my sentences?
Thank you in advance. :)
