As the title says I just shaved my wife's legs with a straight. No disasters.

The hardest part was that I had no routine. I normally face lather and use a brush scuttle. With my wife, I had no feel for how much soap to use on her legs, or how that would work out, so I bowl lathered. I just did a single WTG pass. I did an experimental ATG second pass in one area, but there did not seem to be much gained and I figured that less was best.
