A familiar tale was provided by several players, but Alhakhai told it best:

This friend went to Druid guildhouse to toss a crappy breastplate into pool
for points. But, when did 'donate breastplate' something bugged horribly and
he threw his precious Mirror Breastplate ('breastplate 2', in keep list) into
pool instead of that piece of junk ('breastplate 1', not in keep list). For
some reason, other members in his eq society weren't quite as amused as i was
when i heard this story.
