Peek-A-Boo

I went shopping at Cub this past weekend. Matt stayed home with the kids so I had time to browse and take my time. Sometime during the shopping trip I had to use the little girls room. I wasn't alone in the restroom, in the stall next to me was a mom and her young son. The toddler was a curious little fellow. He peeked under the stall at me, and said, "peek-a-boo I see you. Mommy, the lady is going potty too, now she's waving, now she's smiling, now she's laughing. Hi lady!" His mom tried to get him to stop, but she had no luck. I can see my kids doing the same thing, so I just smiled and waved at him. For some reason, the mom waited until I left before she came out of the stall, can't imagine why?
