Endoh-chan chances are he knew that your mom would say that you wouldn't be allowed the knife, and the only reason he bought it was so he could have a new one.
For nearly every Christmas, we would always put names in a hat and the person who we got, we would buy them a present. We made it when I didn't have a job, and my brother couldn't keep a job, so this way we would be able to afford presents, and everybody would get one. But since my brother doesn't live with us anymore, we all decided to buy everybody in the family a gift! Now I have my mom, dad, and 2 sisters to buy presents for.
Dad: I really have no idea yet. Any suggestions guys?
Mom: angel statue (she loves angels)
Sister 1: a purple sweater (her favorite color)
Sister 2: a panda statue (her favorite animal)
