Sisters?

I was waiting in line at a department store check-out. Next to me is a display of fuzzy slippers in a rainbow of springy colors. Two women walk by. A moment later they burst into laughter. The taller one carrying a large, lime green handbag says to the other, I knew you couldn't walk past those without givin' 'em a feel! They appear sixty-ish but behave as if they're fourteen. They walk on, elbows crooked together, laughing. They remind me of antics when I'm with my sister. I smile for a good half-hour.
