I put my brothers phone in the microwave

This happened a long time ago I think he was 11 or 12 years old and I was 5 or 6 years old I don’t really remember the reason why I did it but I remember that my mom was cooking and he left his phone in the kitchen and I reached in the microwave put his phone in there and closed it my mom pressed the button not even knowing that it was his phone in there so it exploded and messed up the microwave and he got in trouble because my mom thought that he did it I feel bad now thinking about it and I want to forget about it ?
