Should I tell my mom that my brother snuck out the house?  I don't want him to be mad at me.

It is likely best for you to tell your mom that your brother snuck out of the house, as it is important for your mother to know the extent of the situation. By not telling your mother, you are creating the risk that something even worse could happen, as your brother could get into a dangerous situation without adult supervision. It might also be beneficial to come up with a plan with your mom for monitoring your brother’s movements in the future.
