I actually just watched a segment on the news last night where they were talking about tattoo's being more common in the desk/office workplace. I remember some on my teachers had tattoos on their ankles, I thought it was the coolest thing! They were always something like a butterfly, but it was covered most of the time and when it did come out it wasn't shocking or anything like that. I think with more people becoming teachers, and more people resorting to teaching because they can't get a job in their field, tattoos will become acceptable as long as they're covered MOST of the time and not offensive.
