Almost spilt the beans

The scene was a Christmas dinner potluck party at Amit's colleague's house. Everyone is drinking wine or something else. A certain someone from Amit's office notices the usual wine glass from my hand has been replaced by apricot juice. I was totally unprepared for this :-) I just brushed off the question, feebly attempting to offer the excuse that Amit had me memorize: I'm on medication for my knee, and it doesn't allow me to drink alcohol.
