Out of the mouth of babes:

a spunky little 4 year old came over for playdate, she looked me up and down, nodded then said:

"you are pretty enough to have a boy friend"

"thank you"

"so what's his name?"

"well his name is ____ but he's not my boyfriend any more"

"ya I knew it! because boys always breakup with girls. I am sorry you don't have anyone to kiss you on the mouth anymore"

And then she was off to find a tutu, or a barbie. Oh if "mouth kissing" was all it took, the idealistic view of love from a 4 yr old.
