The one thing about being a working mother is - no matter how hard you try to leave the house without some bit of something on your clothing, you can't.
It must be some weird physics thing - there's like a vortex or something from the moment you put on new clean clothes.
Oh - you can think you've left the house without a spot. You can look yourself up and down and inspect...but the moment you get into work, there will always be that one guy who looks at you and says..."Did you know you have a little something right there?"
