The age we live in...

This is kind of a quirky post, but I just had a strange glimpse of the age we live in.  Today one of my students told me that I should friend his mom on Facebook.  I feel so weird about this, but I also feel weird when I run into a parent in the store and I have beer in my cart.  It's like if I'm not the perfect person they will deem me less than fit to be a teacher.  Many of my colleagues friend parents from our school on Facebook and see no problem with it.  I usually don't unless they work at the school.  What do you think?
