Cindy is one of those people who just can't sit still, huh?
I admit that I like to wander around and look at things at museums, theme parks, shopping malls, fabric stores, craft stores, book stores, and the like...but I can sit still and enjoy reading, knitting, crafting, or reading Etiquette Hell...
Just let me know what the plans are so that I have walking shoes, a swimsuit, and whatever else might be handy for the events of the day.
Maybe you should have claimed that you were having a bridge tournament and set up two (or three) tables for a double elimination with partners rotating from table to table (were her kids and your son enough for a second table?)...then everyone could have sat down with some iced drinks, snacks, and had some fun indoors...without a "tour"!
