Since when did tweezers become my best friend?!

Since I turned 30. That's when. If I don't tweeze, my husband might get whisker burn. I'd have a full-on fu-manchu in two or three days. Five oclock shadow at noon. When did tweezers become more important than foundation or hair spray? Since I turned 30. What'll become more important when I turn 40? I shudder to think.
