Well, this depends on the circumstances and the context. An explanation and a confession follows, children, look away now.
About eight years ago I was sitting in my apartment watching TV and a pretty blonde had her head in my lap. The food had been consumed, the wine had been drunk, and we were very relaxed. Suddenly she closed he eyes and whispered "I've been a naughty girl". Now, you have to remember at this point that I didn't know about AS and the fact that we suck when it comes to non-verbal clues. You also need to remember that at times I have the social awareness of Atilla the Hun.
The next ten minutes were therefore spent in useless conversation as Ed Almos tried to convince the lady in question that she hadn't been naughty and (compared to some people) she was really quite good. This was therefore the mother of all lost opportunities. Should anyone else find themselves in similar circumstances all I can suggest is that you give the person concerned a spanking and then see what happens.
