Was this person drunk when they spoke to you. We have all said the wrong things when under the influence and never know when to stop - Perhaps this person is feeling insecure. I'm sure they will be feeling guilty now if they remember what they have said. You should not have to justify not drinking to anyone - its no-ones business but your own - just think of how horrible that person was feeling the next morning. Don't let it get you down - You're still sober and clear headed and that is what is important X
