Your mom told you to study with your brother one day, but when you 2 were studying your brother kept checking his phone but you didn't know why. So you peeked on his phone while you pretended to study, and you found out that your brother Felix has a girlfriend that he never told you or your parents. The next day you told your mom but she grounded you instead because you looked through Felix's phone. Your mom said "You are grounded for a month!" Your brother laughed. What do you do?
