I don't...I can't (I just feel like it would be a bit too pretentious...). but I really, really want to get over myself because I either use an extra chair, or sit with it in my lap, terrified of the upcoming inevitable carnage! I know people who actually ASK for an extra chair for their bag.
Bottom line, I WANT to, but just CAN'T.
I'm a deeply conflicted bag owner. :weird:
