My friend in Brazil found me from my Orkut profile!
Mario was an exchange student my parents put up for a year or so when I was a kid. He sent some cute pictures of us together:
I'm the blond kid having some kind of seizure in the foreground. That's Mario on the left, my older brother Ben in the back.
I remember a couple of things about Mario in particular: He was a bit of a ladies man, took the local high school by storm (he said "I am a girl scout, I like to scout for girls!"). Anyway, so nice to hear from him!
