Stepping on Cracks

The other day I was walking down the street and walking in front of me was a mother ans her two children. Each child was holding on to their mother's sweeter but I noticed one seemed to be walking weird. When I was about to go around them I realized that she was trying to not walk on the cracks! I used to make sure I sisn't step on the cracks so can understand it but it seems so strange to be older and see a kid do the same thing now. Makes me feel kind of nostalgic.
