Make sure your parents have time to talk. If they’re frazzled and running late to work, hold off until things are calmer. Catch your parents when they’re in a good mood, because they’ll be more likely to listen to what you have to say. Don’t act like you deserve a cat. It’ll just make your parents shut down. Instead, approach the situation with an attitude of gratitude. Your parents will be more open to your argument.

You could say, “If I get an A in math next quarter, which will take a lot of work because it’s one of my hardest subjects, will you let me get a cat? I want to show you how committed I am.” If you lose your temper, your chances of convincing your parents will be slim. Try to stay calm and avoid getting defensive, even if your parents give you a firm no. If you feel yourself getting riled up, take a few deep, slow breaths. If you can’t calm down, ask your parents if you can finish the conversation later. If you pressure your parents for a...
