Overheard: I Love You

I overheard this conversation between M (4.5 years) and F (2.5 years) as they were eating a snack:

M: F, I love you.
F: I love you too, M.
M: F, I love you more than my birthday.
F: M, I love you more than the rooftop.
M: I love you more than the moon.
F: I love you more than the sky.

(this sweet conversation continues back and forth a few more times, then evolves. . .)

F: M, I am going to go to the bathroom. Don't eat my cereal, okay?
M: Okay, I won't.
F: Make sure you don't eat it, okay?
M: I know, I won't.
F: I'm just gonna go to the bathroom and then I'll be back, so don't eat my cereal M, okay?
M: Okay! Okay! Just go, I'm tired of hearing you talking!

Ahhh, feel the love!
