I am not exactly a prude and I suppose if a guest did this I'd think, 'Put it away, love' but wouldn't be surprised at the actions of a very drunk woman, however, I recently went to a wedding night/disco-type thing where the bride was very drunk and did the following:
She lay on her back, hitched up her dress (it was traditional frock-you know, cream, satiny, long etc) and started scissoring her legs wide apart so everything was on view.
Crikey, I'm no prude as such but this behaviour I found to be strange. AIBU?
