Hard Core Enforcer! I am very good at discipline with my 'Grands'. They think I'm really 'nice' or that I 'won't do anything' if they step out of line. I'm so good at quiet discipline that they don't even know when they're being disciplined!
Most of my rules are about safety and respect, and I don't just preach them, I practice them.
They rarely misbehave around me. Of course, if they were with me 24 x 7 that might be very different.
I am, however, considered a 'manners and grammar nut'! Guilty as charged.
