In the photo below I was trying to identify of my mother's siblings. Mom couldn't remember the photo. She asked me to tell her who the other people were in the photo and to describe what everyone was wearing. She still couldn't place the photo. I told her that her sister Dot's slip was showing, then she remembered the photo and where it was taken. You never know what's going to trigger someone's memory.
Left to right: Babe, Dot, Adrienne, Flo and Sally.
