middle kid, age 11: "there's the bikini tree!"
youngest kid, age 7: "those aren't bikinis, they are bras"
middle: "same thing"
youngest: "actually, they are not the same thing"
I don't know why this struck me as funny, but it did
A nice moment later in the day: the youngest one (on skis) towed his snowboarding brother over a flat part so they could both get to the fun part faster. I heart them.
