Day 452 - others sorry for drinking?

It’s day 452 for me and finally accepting my life is so much better sans alcohol. I went to a pool party yesterday knowing others would be drinking. I had my tools in place and was prepared for any cravings. I wasn’t prepared for an intoxicated guest commenting “I’m sorry!” I asked “for what?” And she said “because I’m drunk and you are NOT”. I just said “you’re good!” And things seems to move on. Any tips on what to say when this comes up? I was tittering between “I wish I could!” And “you call THIS drinking?”
