Color blind?

I just got home from visiting teaching and as I was leaving our last appointment our sister pointed out to me that I had on one brown shoe and one black shoe. As you can see I have the same style, just different colors. The closet light is fairly dim and I didn't take the time to check before I left home. (I will next time!) We had a good laugh and I came home to change before I run errands. She did make me feel better though by telling us that she had once gone visiting teaching herself with her shirt on backwards and inside out with the tag in the front. No one told her and she was mortified when she got home and saw herself in the mirror. She vowed she would tell someone if a similar situation arose. Thanks!
