in the toy store

It was on Saturday when my friend and I went shopping. In toy store we saw Lego Halo. Nearby was a boy about 8-10 years old

me: Oh Lego Halo! *takes box in my hands* Cool!
boy: If it's for a child he should play Halo
me: It's for me
boy: You played Halo??!
me: YOU played Halo?! OO (as you know Halo is 16+)
