^^^^I don't either. No matter how excited I get about going on vacation, I never announce on my FB statuses, etc., that I am "going to NYC tomorrow" or "3 sleeps 'til Toronto!" Although I only have friends on FB, you never know who might see a friend's open newsfeed and discover that I am not at home. After I get back, I post pics and casual friends say, "I didn't even know you were going anywhere!"
