DP and I went to a small party at my boss's home; he'd cooked a roast dinner. DP looked at it and said 'ooh, potato gratin for the third day in a row!' to me. I thought this was rude so said something like 'it all looks really delicious!' Since I'd not acknowledged the comment, DP repeated 'we've had potato gratin three days in a row now!' DP did also, to be fair, say it was delicious. We are now disagreeing. DP thinks it was a perfectly fine comment and doesn't really believe me that it was rude. I think it was rude.
Who is right?
