When I saw this on krisatomic, it cracked me up. I can soooo relate to bitchface.
It's all about the eyebrows, let me tell you. My father has the "man" version of this. It runs in the family... I promise I am usually not annoyed or pissed off, it's just the way my eyebrows come together and my mouth at rest looks frowny. ;)
I haven't gotten any "cheer up" or other inquiring comments lately, so I guess I've learned to "put on a happy face". Either that or they just plain gave up wondering what the hell is wrong with me. hee hee.
Have a great day and SMILE!
