i wanted to separate these thoughts from the previous entry...

the other day i was thinking about tears.
they are strange things.
i understand that the purpose of liquid in the eye is to cleanse them of dust and such..
but why do we cry when we are upset?
what physical aid do those tears falling from our eyes realy give?
why does crying make one feel any bit at ease about a situation?
does it?
if you know the answer, please share it with me...
my tears help add to my own confusion.
