I wore mine yesterday as well. I normally don't wear jewelry so I did get a lot of "What's that on your sweater?" questions from my students. Of course, I happily took the opportunity to explain to them the benefits of going Greek!
Even better, we are celebrating collegiate/Greek pride all this week. I (along with other teachers) contributed some items (pledge paddle, pictures, etc.) for a display in the main hallway at school. We also are encouraged to wear our Greek gear on Friday to show our spirit!
