five year old kisses

So today, I pick this girl up from school,

and here goes our conversation:

Molly: Connor kissed me.

Me: (surprised) He did? Where?

Molly: On the lips

Me: On the playground?

Molly: No, in car line, while I waited for you.

Me: Why did he do that?!

Molly: Because I told him to! (We all know who will be wearing the pants in her future relationships)

Me: Molly, you're 5 years old, why would you have him do that?

Molly: Because Karlee, when people are in love, they kiss eachother.

Me: (hiding my laughs) You're 5!

Molly: Well, my mom and dad are in love and they kiss.

So, I went into the whole, you're-too-young-to-be-kissing-boys lecture. But in all honesty, how do you deal with a situation like this? It's so innocent, but who really wants their five year old kissing boys at

 school? Definitely not her parents. I mean, c'mon.
