I hate to hear that Eddie.  Sounds like your grandson has a good head on his shoulders.  I'm hoping something like that doesn't happen in my kids school.  My oldest, 8, had to write a report about his favorite place.  He wrote about his Papa's knapping pit.  Think your thoughts thru and keep your head when talking w/ folks like that principal.  Teaching gun safety @ a young age is the best thing we can do for our kids.  Find the studies done about kids who grew up w/ guns and the ones who didn't when they were put in a room w/ a gun.  The kids who grew up w/ guns paid no mind to the weapon, the kids w/o gun knowledge couldn't keep their hand off the weapon.  In states like North and South Dakota, hunting is a family value, everyone does it, even Mom's, sister's and grandmothers.  That's how it is w/ my family from ND anyway.  Good luck w/ this Buddy.  dpgratz
