New books always remind me of Easter.
In our house growing up, the Easter Bunny brought new books (as well as a chocolate egg, but I refused to eat chocolate as a child, so I always associated Easter more with getting books).

Kind of embarrassing when I started nursery school, though. I thought everyone's Easter Bunny brought them books.
Then when our teacher was asking about Easter one time, and everyone was shouting out the answers.
Teacher: "And who's got long ears and comes at Easter?"
Everyone: "THE EASTER BUNNY!"
Teacher: "And what does he bring?"
Everyone else: "CHOCOLATE!" Me: "BOOKS!"
They all laughed at me. *sniffle*
