When someone in their family die then the atmosphere in family is so silent that no one is talking accept crying or making a sadness face.

The proper meaning of piss is went away so when some one leaves and he is died and if he is our younger brother or sister then we fills piss for themselves because we were living together at good time as well as bad time and now he/she has leave then it is very bad problem to live without them.

Yes,we obviously piss themselves when they die ,the movement we passed through out our life how can we forget we had live a happy life and sometime we fight with each other and parents comes between to make separate how we forget that. So I really piss themselves when they die.
