So Sweet, and So Annoying

Around midmorning today, as I was snuggled in the rocking chair with Caitlin, cuddling her to sleep while basking in the soft sunlight, I was startled out of my dreamy bliss by a monstrous Victoria banging open the door and loudly growling "I LOVE YOU MOMMY!" over and over again. Caitlin's little eyes fly open and we both jump a bit. How can the sweetest words ever, from the sweetest little 3-year-old ever, be so annoying and yet still so cute?
