I'll cry when I can't suppress the last bit of my anger/frustration anymore, and I usually make sure I'm alone. Obviously I will cry when someone close to me passes away or gets into a life-threatening accident. Just thinking about it hurts too much. I'll cry when I finally am able to make my dreams and goals come true as a grown-up. (hey, people also cry when they're happy) I'm not an emotional person and I stick to a blank face until I'm alone and it's finally safe to let the tears fall, so I rarely cry.
