Gross Or Cute?

Valentine's Day passed in a blur due to the festivities of M-Boy's b-day on the 13th. However, Little Man was sure to give me a "special" Valentine. First, there was the handmade card. Inside there was a picture of a brain on the left side with the words "smart daddy" underneath and then on the right side a picture of a heart with the the words "sweet mommy" underneath. Oh, I do not mean the cutesiepie hearts that surround cartoon images of Cupid. This heart was like the one in your chest with veins and arteries everywhere that actually was pretty graphic for an 8 year old. He said "Daddy is the brain and you are the heart. Our family is like a body." What a sweet kid, huh? Then he handed me this plastic baggie with a used q-tip, a toenail and a few strands of hair. He handed it over to me with this huge smile and eager look in his eye like he was giving me the best treasure the planet had to offer. I asked him "what is all this stuff?" He said, "it's my DNA. I am giving you my DNA so you can always keep it close." How would you respond? I just hugged him tight and thanked him for such a thoughtful gift. It was kind of gross but I feel so loved.
