I guess if you are surrounded by people drinking that have a jet set lifestyle and everything that one could possibly imagine including peace of minds and serenity, and are enjoying a glass or 2 of 1949 red wine then this might cause a light reaction in you which you have obviously countered by remembering the bad old days and the way you feel and look great today:-)
If its the sort of parties that i went to with the typical run of the mill 'normies' i wouldn't worrry too much about it;-)
