I'm soooo not a fan of the act of people guessing your weight. Guys seem to do this pretty frequently and I hate it! I'm assuming it's just because they don't have the same hang ups as women do about weight, but come on. You guess too high and I immediately give you the death stare, while you stand there looking confused.
My uncle did it when I was home for vacation and my friend proceeded to do it yesterday. It's like some sick joke that only they think is funny. Tip of the day guys...no girl wants you to guess their weight...EVER! It's really not a good situation for you to be in at all. I am not a side show act in a carnival who will give you a prize if you can guess my weight. The only prize you will get from me is an attitude problem and me wishing you would just leave. Hmm...wonder if Abbra Kadabra would work in this situation? ;)
