hmm, its always a trick situation when telling your parents for the first time, I told my dad, and he was calm, but completely pissed off, he didnt tell my mom, and he even gave me a few nugs, but he was still pissed and didnt talk to me for weeks. Then I got caught by the cops and when my mom found out, all she could do was cry. My dad, was then even more pissed. I thought he would respect me because I told him, but he didnt and lost so much respect for me. It was wierd, I though he would be proud that I told the truth, but he said "You should have just lied" Now, the are both pissed and they dont trust me at all, my mom has all my money and Ive been grounded for a month now and my mom hasnt told me when she'll un-ground me.

As for the other parents, thats completely up to them if they tell. The only thing that will suck is if you tell them and the other parents dont tell on you and you get in trouble.
