The answer is yes, provided it came from a curly haired, smiley, joyous two year old. As I was cleaning spit off of my glasses tonight after putting the kids to bed, I giggled a little at how it got there. Carter randomly started singing "Happy Birthday to you" while putting him to bed. At the end of each verse, he blows out the candles in his head. Well, Carter "blowing out candles" is about the cutest thing ever so I naturally thought of something else to get him to keep doing it. Hence the song "I'm going to let it shine" which after the words, "don't let anyone blow it out," he gives the most ferocious "blow" about an inch from my face. So, yes, spit can be cute.
