Frosty and Playdate

I was driving to work with Lanie the other day listening to "Frosty the Snowman" on the radio.  I asked Lanie if she liked the song and she said, "yes."
"Yes, mama, I like Frosty." pause, and a minute later, "I think we have Frosty over for a playdate."
At this point I've deferred a simple, "yes, that sounds nice," instead of reasoning it out.
"Actually," Lanie said, (it's about a 6 syllable word when she says it), "let's go to Frosty's house for a playdate!"
"Great!" I agreed.
