And if that guy put up a photo from that day on Facebook now, I would absolutely rip him a new one for posting it. (Incidentally, I got kicked off a Facebook nostalgia group a few years ago, when someone put an old picture of a couple of white guys dressed as Indians as the header, and I said, you know, it's one thing to post that in a particular context where you're talking about why they were dressed that way, and another to post that where non-members will see it as representative of this group, which I for one am not happy about.)
