I remember once upon a time a mother-daughter couple where crying out loud in the bus which I was travelling, verbally expressing the grief over the loss of their father. I was surprised that people could express so much emotions. I'm no good at expressing extreme emotions, especially grief.

The people in the bus where tolerant enough to not ask the grieving couple to stay quiet.
