Don't do what my grad school roomie and her scull-building boyfriend almost did.
me, coming into the basement: "Hey guys, cool. What's that?"
Carol: "Matt is teaching me to build a rowing scull."
me: "Neat. Is it smart to build it down here? Pretty tight spaces."
Matt: "Yeah, we made sure we could get the keel piece in and out. It's a tight fit but we can just make it up the stairs and around that corner."
me: "Hm. You sure? That's an awfully tight corner."
them: "Oh yeah."
me: "The scull's wider than the keel right? Like a foot wide? Like too wide to go around the corner even though the keel can?"
So Dale say "Beware building boats in basements when hormones cloud judgement."
