what to say when wrong or made a mistake

[Mdenglish]

Hello there

Two people having a conversation about someone's age. (Meg is thirty-five years old).

A : I think Meg is thirty years old.
B: No, she isn't. I know for sure she is thirty-five.
A: ?

What would be the best line for A to admit he/she is wrong in this conversation.
Do you know any other expression you could think of ?

A1: Oh, I'm sorry.
A2. Whoops. I got it wrong.
A3. My mistake, sorry.
A4. Oh. I always thought Meg was thirty.
A5. I got it all the time wrong.

Thanks in advance,

Hi Mdenglish,

A1-A4 are all acceptable, but I'd personally never say "Oh, I'm sorry" in this situation, since that sounds a bit too severe and formal of an apology for such a minor error. If I were apologizing directly to Meg for getting her age wrong, then I might say "Oh, I'm sorry". Usually people aren't that upset if you think they're younger than they really are, it's the opposite that gets you in trouble.

A5 could work if you said "I get that wrong all the time", or "I always get that wrong".

For a slang term in a very informal situation, I might also say "My bad" (- but only if talking to people my age or younger, as this is relatively current slang). I might also say things like "Oh, I stand corrected (then)", or "(I) guess I was wrong/off/mistaken (then)."

If you wanted to express disbelief, you could say things like "Oh, really?", "No way?", "Are you kidding/serious?", "Is she really?", "Is that so/right?".

"No way" is rather informal usage, as is "Are you kidding/serious?".

There are of course profanities or oaths ranging from mild to extreme which a person could flavor their statement with also. That would depend upon the social context of the situation.
