I remember when I was younger...

No , I don't remember that I did something like that with any food , I was not enter toilet with fruit or food

when I was kid my aunty always forcing me to drink milk every morning and afternoon. I don't like milk till now, when my aunty is around, I will pretend that I drink my milk, but when she is turned her back I will run into toilet and finish my milk into it

I don't think my mother would've cared that much, but then again, she probably would've been sharing it between my brother and I anyway - or eat it herself.

No, I never did anything like that. My parents wouldn't have seen any humor in something like that. They weren't gifted with good senses of humor. You have, however, given me another argument for having a composting toilet...

I don't recall doing anything like this myself, not saying I didn't just can't remember and haven't heard any stories of anything like that but my daughter has done things like this not in a long time which I hope because she has grown older and hopefully grown out of it but I remember a few times especially with meat she didn't much care for it and so on numerous occasions she would take a bite or two and the would chew it and chew it until it just turned to mush and then she didn't want to swallow it and a few times I would find it in the toilet or in the garbage can and even once I found her chewed up meat inside of her jewlery box. Oh it was so disgusting and smelled so horrible, she got in some big trouble for that one. I havent found anything like that since but I think now she is older and likes meat a bit more so she doesn't try any of that or atleast not that I have found

My son did something similar recently. But not with an apple, or any food. He was playing with paint in the bathroom and made a mess. So, he tried to clean it up with paper towels. Not wanting to get caught, he flushed a bunch of dirty paper towels down the toilet. It got clogged up! I ended up fixing the toilet.
