Once.
Oh, you were only half as bad as I was. I got it once in grade 5 and once in grade 6. Both times I was innocent!
6 years of public ed. That's about all hubby had. Went to a private school for 3 after that and then took college after that. He did pretty well with his Lt. pension from firefighting and his HD mechanics papers from the college.
Now he's in the school of life and I am training him. hahaha
That's the tough one and you don't get any 'papers'
