I remember some corporal punishments, and i remember that i dont understand why...

Corporal punishment dont work, and destroys your child's self-esteem.

I remember that horrible day, i was forbidden to watch TV for 24HOURS.

... joking

I remember my mom thinking that kneeling on rice was the worst punishment! On the porch, she'd pour uncooked Uncle Ben's and get us to kneel on it with bare knees. As kids, we'd act like it was so painful to avoid any WORSE punishment, but actually, you just had to pick grains of rice from your knees afterwards.
