I usually cry chopping onions T_T

Some people say the eyes are the window into the soul, so they are just showing forth the sadness and despair of the soul maybe.

I think people cry for different reassons. Some cry because they feel that something wrong happened so it was not fair. Maybe they caused trouble to someone or to themselves. Maybe they are frightened and donot wonder some pepole cry because they are happy or miss close relative or friend. so it depends

bcoz they are emotionally not balanced

I usually cry at funerals. The last time that I cried was at my mother's funeral last year as I realized that I would never ever hear see her or hear her voice again.
