Why an unplanned night of friends can tip the scale in the wrong direction

I feel I had planned yesterday out quite well.  Got all my meals in, was at the proper calorie amount but then I threw it all off balance by a night out with some friends after a meeting.   Instead of just being social and only drinking water I had some adult beverages, those calories sure creep up on you when your not looking. 

Last night is truly a case of I know better and I need to be better about watching what liquids I chose to drink.  I could just as easy have water with lemon in it all night and have it look like I'm still drink and save myself all those calories.
