You have to keep in mind that yes some cry after a loss but even a winner can be crying, once the adrenaline eases up the pain hits hard, as does the damage you feel and caused the other, a lot cry out out of the anger and anger of the situation they been placed in, and there is a level of crying from all the emotional release and stress that suddenly has vanished for that moment , a catfight ,or any other fight releases a built up emotional time bomb, that can cause tears.
