Why do we cry ?

why do we cry ?

We all cry...we cry in love, we cry in sorrow, we cry when we are too happy....I asked this in my Facebook profile and 2 doctors gave answer as per medical aspect.
If it is certain emotion linked with our brain, then why women cry more than a man? The 2 doctors gave their statement regarding this too.
But to me its really something which cannot explain with medical terms...We cry more in love thanin pain, cry more when someone die than when we leave our friends and relatives...So why this crying differs in different situations??
If any one can give me an answer, which really pacify my inquiry, I will feel really good and composed.

MY DREAMS !!

I had a dream to change many odds of life. I started for that from my very young age. i am a rival and outspoken..so their was more enemity. Its an incident I would like to narrate...I was
only four years old and that was the time of Ram navami..I was fond of my father..and he still is my dream personality. As i was too small i was asked to go home in between a drama, at my fathers Club. I protested..but i had to leave. I cried the whole way back home. my mom consoled me and laid me by her side. I could'nt sleep and when I found she is fast asleep ...I silently walk out of the room and start running to reach the club. On my way i saw my father with other members of the family and neighbours coming....I stopped..my father saw a little girl standing in the middle of the road and out of curiosity, he came near me. And.........!!! That was the day.. still in my mind as a remarkable day..and we became a friend..Isnt it lovely ??? You may ask why its your DREAM ??...My answer will be to be a good daughter and for that to overcome all difficulties should be a dream for every human being....
