Aw Im sorry about that {:( heres some solutions :)

Be honsest and say " Hey *Persons name* I didn’t do what I got in trouble for, it was *persons name*. I promise I’m lying, if I did do it I’d tell you”

For the movie, rember it’s just a movie :) sometimes what helps is looking at the actors of the movie so you feel better about them not being sad and you not being sad.

And for the food, try and make yourself a snack! And if you like it, keep it a secret (or not) :)
