Mother Nature

We were talking about how I've planned out my first kiss and how it has NEVER happened:
C: Yes but it has never actually happened... I thought you might've taken a hint by now... It's nature's way of telling you it's not gonna happen in a planned manner...
M: I hate nature.
C: I think the feeling is mutual...
M: That's for sure!!! We have kickboxing tournaments all the time. Stupid nature. She always wins.
C: I figured as much... She just has the wind, water, and fire on her side...Not to mention giraffes... Giraffes always win...
M: And plants and stuff. Not that any of that helps her in kickboxing. She's just plain better.
C: Well yeah... But I bet one of her fists are a giraffe.
M: Wrong. Her hand is a tree and her other hand is a whale.
C: No... I'm pretty sure one is a giraffe and the other is a fat taco.
M: Really? You are so not the one who wrestles her on Mondays and kickboxes every other day of the week. Except Sundays.
C: Huh... Actually that's my exact wrestling/kickboxing schedule... And come to think of it my boxing gloves are remarkably similar to a tree and a whale... Yours aren't a giraffe and a taco by any chance are they??
C: Pretty sure someone told each of us that the other was mother nature... NBD... Ugh they probably misread my name of mother man made stuff.
Why do we say the things we say?
