I Was Whipped By A Belt

I am 12 years old boy and I live with my little sister she is 7 and grandma my grandma is really strict but I really love her when my sis does something bad or breaks something (while I'm babysitting her and supposed to look after her ) we both get whipped i get whipped really hard with a belt then sent to the corner then it's my sis turn then she get sent to the corner too we stay in the corner standing putting our hands on our head and keep saying sorry over and over and what we did wrong after 30 minutes or an hour my grandma pulls our pants up and hugs us and kisses our forehead and tells us to go to our room and calm down and think about what we have done (if my sis did something wrong while I'm not babysitting her or supposed to take care after her she is responsible for her mistake and I don't have anything to do with it ) my grandma use other punishments when we misbehave like grounding and taking stuff away but most of time we get whipped and my grandma whip us so hard 😭😭😭

Did they get it too?
I got whipped with the belt twice for breaking something in the house.

I broke a window once. My dad was so angry with that, I don't think I sat without squirming for a week.
Then the other time, I broke a dish that I tossed to my cousin. That was the first time I got whipped with the belt.

Because I was babysitting them. When I babysit them, I'm responsible for them and if they misbehave I get punished.

No, they only get grounded.
What did you break?
Once a I break 5 cups.

I'm not seeing the logic of the situation...

Your siblings broke a vase, you got punished.

What logic do you mean?
