Love Notes

My eldest son, K, is learning how to write and read phonetically. Lately, he has taken to writing me love notes, totally of his own volition (not prompted by me in any way, shape or form). The first one said:

I luv u

and today another:

Momme luv mme up in [insert a picture of a heart]
K

K translated this second one for me. He said it means, in his heart he loves me. I told him how special it makes me feel to get his notes, and he was just beaming.... and I thought D was the "lover-boy"...
