This boy:

is obsessed with birthdays. 

A few days ago I was putting away laundry and we had this conversation:

L: Happy Birthday Mom!

Me: It's not my birthday, silly.

L: Sing happy birthday?

Me: You can't sing to me if it's not my birthday.

L: Happy birthday to . . . my rock? (Holding up a little piece of gravel he was playing with.)

And then we all sang "Happy Birthday." 

To a rock.
