Why would I steal yeast as a child and really enjoy eating it and then frame my brother for it?

idk kids do weird things i found some pill capsules and dumped them in my sleeping brothers ear once when i was 5 i used to steal mints and hide them in the candle holder in my room

For the thrill of the crime?

What's weirder to me is the framing of your brother for it. how do you frame someone to show that they stole the yeast and when in the world would anyone even think to look to the children and wonder where it had gone. Had you done this times before?
