It's one thing to wear mismatched socks...
... but to wear mismatched SHOES? That's so bright of you, Cate.
You see, I have two pairs of Chuck Taylors that look almost the same. They differ a bit in color and size. The one in the light gray is smaller than the dark blue. Last Friday, I was rushing to get out the door to catch the earlier train. I already forgot to wear a watch that day. As I was walking to the station, I noticed that my left foot felt less comfortable than the right. I thought I wore my blue Chucks. I didn't think much on it at that time though.
Then I got to my work place. I finally decided to look down and examine my shoes. Lo and behold, my suspicions were correct. In my haste, I put on a shoe from two different pairs.
If anybody noticed, they were nice enough to not mention it to me. ;-)
