Dan is my little brother. Not my littlest brother, that's Brian. Although I think Brian is taller than Dan.
Anyway, Dan is four years younger than me. When he was little he had bad eyesight pretty young and was always wearing half-broken (because he'd constantly break them) glasses with tape on them. We called him "our little nerd". He also had crazy curly hair his whole life unlike me - mine only got really wacky around puberty. So he had crazy nerd glasses and crazy nerd hair. Poor Dan, he didn't stand a chance.
So now Dan lives in Hopkinton and is a computer scientist. Ha ha. I think he'd rather be sitting on a beach playing his guitar or something. He taught himself to play when he first got a guitar around age 15 or so. He got really good really fast. Also around this time he spontaneously re-took up playing the piano. I think he took lessons for about five minutes when he was really young. Now he's some kind of musical genius. Dan is very smart, as all of those in my immediate family are, of course.
Dan and I are branded as "hippies" by Brian, but the truth is, Dan is the only real hippie. I'm only a tiny bit more of a hippie than Brian but I don't think I can really qualify. I like pretty shoes too much. Meanwhile, as he once described during a visit, one of Dan's most closely held ideals is his "disdain of fancy clothes".
