I was just telling a friend yesterday that I had been very disturbed that one of my children's previous teachers was so tatted up. I have a tattoo as well, but a small one that can be covered at all times. I thought that it showed a lack of good judgement on her part and made me look at her teaching more carefully. She turned out to be a great teacher, but it's just a warning. Even if people don't say anything, it may be something that is held against you.
