The Meaning of a Word

Last weekend, my oldest son, asked me, "momma, what does 'spoil' mean?" After a few probing questions, I realized that he was trying to reconcile two different meanings of the word: (1) that Nana and Papa "spoil" them whenever they're together, and (2) --from a book we read-- Rudyard sadly overhears his friends saying, "I hope Rudyard doesn't come! That would spoil everything!" (Rudyard doesn't realize they're talking about walking in too soon to his own surprise party, but I digress.)

So I explained the meanings to him, and he seemed satisfied. But apparently, he didn't really get it, because...

This weekend, after Nana (my mom) had taken the boys to the zoo, while they were driving home, he excitedly said, "Nana, I love the way you spoil everything!"
