Sometimes you just have to laugh at yourself....
apparently, I've been walking about with my pants unzipped for quite a while. Well, it's almost 4:30...and I last used the restroom at 2:40. (it's a weird series of events that lets me know what time I last tinkled...) Anyway....at least I'm wearing cute panties.
Thank goodness I discovered this myself instead of someone pointing it out!
