a kiss?

what does a kiss mean?
either a peck or making out itself.
"what IS a kiss?"

went and Google-d my questions. got all sorts of stuffs.
one of 'em said, that it was a way of showing affection.
or it could be, the transferring of hormones. wtf.
or just for the heck of it?

is there more of an answer to just the scientific and obvious?
is there no elaborated answer?

for me, 
-a kiss on the lips, signifies an openness and honesty in a relationship. that the partner allows the other to actually take a step closer into her life, physically and relationship-wise.
-making out, on the other hand, is more than just a feeling, but the action of embracing one another, in each other's arms. but rather being all comfortable and trustworthy enough to trust the partner not only with their lips, but body, too.

i don't really know why, am i thinking so much after watching a movie that i had watched over 5times, but only now just thinking bout it.
blame it on the nostalgia, blame it on the curiosity, blame it on me.
wtfcares.

changing a place to put my thoughts,
rather than sharing it to 796,
i will share it to 53 instead.

but what does it mean to you?
