Ziv's a little menace, but it's difficult not to like them. They give me a run for my money in quick replies. I always admire that. Sometimes they need a wheelchair when their joints give out, and if people are being disrespectful, they 'accidentally' clip people's ankles with it.
They really believe in the power of badges and pins to quickly communicate parts of who you are to others; it's not just about decoration for them. They've actually written whole papers on the psychology of symbolism.
So, some of the badges are normal, but Ziv still thinks they're special. Others, though... They've got something more extraordinary to them. Not that they could write about the extra-special ones in their papers, but... They can share them here.
