Tristan helped himself to one of the apple tarts. "Oh, you're quite right. This should be the last glass of wine. I must admit, I usually don't drink this much, and we haven't reached the whiskey yet, so I must ask your forgiveness in advance, if I seem like an idiot for the rest of the evening." - an idea that would usually mortify him, but that now provoked a snort. And then his own unexpected snort provoked something between a laugh and a giggle. Oh dear.
