The giving ones are my favorite ones. One of the reasons why I did mine was to foster a sense of giving. I could say, let's all chip in for this guy/gal since a few of those folks saw me receive mine.
I've seen it given as recognition as a thank you to an outgoing lodge chief, scoutmaster... etc.
I've seen it given in honor of someone who has passed away.
I've seen it earned by a group - an OA lodge, a woodbadge staff, camp staff, etc.
