I've met sisters in random places!
1. I was at church one day and was wearing my lavalier. My priest says "Delta Zeta!". I was kinda confused and he explained that his wife is a DZ from Florida State! How fun

2. My next door neighbor is a DZ
3. My eye doctor is a DZ - I was wearing a mixer shirt to get my eyes checked one time and she told me she was a DZ alum, too
