A similar thing happened to me a little while ago, my little brother wanted to take my turtle to school for show and tell. After calling his teacher and getting her permission, I went to the school after lunch and showed everyone the turtle and since it was the afternoon the teacher just said hang around help the kids and then you can take your brother home after school. So i went and sat near my brothers table and i noticed one of his friends had a Pokemon backpack with some Gen IV pokemon on it and i said cool me and my brother like pokemon to, My favorite is Charizard and the whole table looks at me and says whats a Charizard, I was like old im so old
