I recommend that you refrain from "friending" students and parents of students. Also, be mindful of what is posted by and about you on other social media.
Also, please join the BTA Facebook page! It's another great way to stay in touch with your teachers' association and your colleagues. Just "friend" me, and I'll add you to the group. Our group is a PRIVATE group, no one who is not a BTA member or retiree can see what we post to each other.
