My oldest daughter was at work until the early evening and my other daughter went to a friend's house within walking distance. My mom was bringing my older daughter home and my younger daughter appeared with her friends for a few moments then left.
After my younger daughter left I had a "do do do do, do do do" (creepy music) moment when I realized that sometime in the near future my daughters will be independent of me and will come and go in young adulthood as they please.
It took my breath away until I realized my younger daughter came home to get her newest anime costume and her old anime costume to take back to her friend's house. They were going back to her friend's house to "cosplay" (costume play).
But to you and me?... they were playing dress-up.
