The bumper sticker is sort of like tooting your own horn, and sometimes that rubs people the wrong way. That's all. If your kid is THAT spectacular, people will know about it, you don't need to keep reminding people of it with a bumper sticker.
We keep saying that OVER and OVER. Someone isn't listening!
Giving kids awards, principals announcing things, honor roll being published in the paper are NOT what we are talking about.
