My wife[53], on/off. You may see her running errands on Saturday afternoon looking like the left side of the pic, but know that I'll see her Saturday night looking like the right side.
My wife. Not so much of an On'Off as a time lapse. On the left is age 23, pre-kids, done by a professional photographer. On the right is age 40, after two kids, done by a not-so-professional photographer.
