one-sided bonk

I was pounced upon in bed this morning! Dennis came into my room loudly asking "Are you not up yet, Mommy?" and reporting "the sun is up and it's daytime now". Since it was close to 9, I didn't really have a need to complain. He was right. He climbed up on top of me and said "let's play bonk" as he bonked my head with his (and I still think ever so fondly of my brother whenever I'm surprised with a game of 'bonk'). I leaned up to bonk back, but he stopped me and said "No, don't bonk me, Mommy, my head is special". So I put my own un-special head back on the pillow and took 5 more minutes for myself.
