The RW thread got me thinking about this. I've noticed some people on here are quite protective of their letters no matter what they're printed on or who is wearing them. While others are more of the opposite. An example from my campus is that no pledge at ANY time may wear the organization they are pledging's combination of letters while other school's denote that as hazing.
I know that I've become more laid-back w/my letters over time, and I don't freak out if a friend who's cold wears one of my sweatshirts off of campus now (not relaxed enough for on-campus

). But I know of people who if their own mother was freezing too death wouldn't let them wear a party-shirt, heh.
