The dragon glass and my two prom glasses pose atop a FFXII guidebook.
I got a glass as I was leaving prom, and I got the second one when I went into the room where they were stored 'cause I'd heard there'd be a meeting there of a club I was in, and the teacher asked "Jared, have you gotten a prom glass?" I said "Yeah, but can I have another one, anyway?" She said "Sure." so I nabbed one and left.
