Christmas

I asked my son what his favorite part of Christmas is and he honestly replied, "the presents!". Should I as a parent encourage him to express his true feelings or should I correct his thinking to be more PC, Jesus, giving, charity, and hospitality? Being a Catholic women, I know to encourage the christian values, but at the same time, I ponder, Isn't it okay for him to be truthful? When do I get to admit I like the presents too? Although I do personally like the charity of the season. (PC disclaimer!)
