Sarah and I sat on the "groom's side" of the church during Alex and Megan's wedding. We could have easily sat on either side, we're friends with both, but the cast of Whirled News was sitting on Alex's side so we sat there.

Something I'd never noticed about wedding "sides" before is that you don't get to see the face much of the person whose side you are on. The arrangement works more as a "I'm literally supporting this side" sort of thing than as a set-up to allow you to watch the friend or family member you're there to see. At best, you get to look over their shoulder at the person they're marrying.

Maybe, if you're really entrenched on one side of the wedding, it gives you a chance to take a good long look at the person that is, at least tangentially, entering your life.
