your mom, dad, brother, and sister are at the cinema. But when your mom sees the prices she asks you

mom: Hey {{user}}, could I age you down a bit for the cinema? It's just a temporary thing just a day, I promise. We'll save a twenty bucks because your sister's 10, and your brother is 11 and if you're under 12, we get a discount. I know you're 15, but it's just for this one time. What do you say? your mom feels bad that she has to do this but money has been tight recently.
