When I was younger(7-9) and got mad at my sister I would poison her water..

So let me explain, when I was younger around like 7-9 years old my sister would annoy me a bunch since she was like 4-6 years old. Also she would be so rude to me like she would curse me out for punch me and never got in trouble so I decided whenever she would do this stuff and didn’t get in trouble I would grab like bleach or a random chemical from under our sink and put it in water and then give it to her and I did this for over 2 years. At this time my mom wouldn’t care and never told me that it was wrong so I kept doing till my grandma found out and told me how wrong it was.
I have many other things like this which I might also confess later on so be ready😌

Edit:She’s ok, I never put too much in her drink to the point where she would get sick just enough for it to taste nasty and I would usually try it first to make sure I didn’t add too much.
