Needed to take some antibotics after having some dental work done. Went to the club and didn't really think about it:
Her: You're not drinking tonight?
Me: No, I'm taking some medication and I'm not supposed to drink alcohol.
Her: Nothing serious I hope?
Me: Nothing a little penicillin won't cure.
Her: Oh, well, nice seeing you, I, ah, gotta go…


Too honest! You could've MILKED the pity angle. I guess that leaves the guilt card though -- as in reminding her how fast she abandoned ship in your time of need.
