Aden and Ian met through the Ultimate team at Grinnell. Ian missed having a brother around to fight with constantly, so he decided to fight constantly with Aden instead. Somewhere in between the regular cafeteria ice cream fights and the time Aden TP'd Ian's desk, they decided to room together senior year.
Andrew is Ian's brother. Andrew tried to smother Ian when Ian was 1 year old, but their relationship improved after that.
Jim and Ian met in high school on the XC ski team. They've remained good friends over the years, even after Jim cut his glorious hair and moved to Wisconsin. Besides the usual wedding party duties, Jim will be lending his booming voice to any announcements that need to be made during the wedding.
Ian met Kurt when he was about 12 years old and didn't think much of him. They met again in high school on the Ultimate team and got along a lot better that time. Ian and Kurt lived together for two years in Minneapolis before parting ways to opposite ends of the country. Luckily, Kurt and Ian's parents now live next door to each other to keep the connection alive.
