I cry very rarely. I don't know how uncommon that is, but people are usually suprised when I tell them just how rarely I cry.
I'm fairly certain I cried a total of twice during all of high school. During that time, I went through the divorce of my parents, cancer, chemotherapy, and a heart breaking two-year crush on a friend who always managed to keep me at arm's length, but just close enough that I thought there might be a chance.
I'm a very passionate person, my feelings just don't usually manifest themselves in tears. When my spirits are crushed, I usually retire to contemplative silence, music, writing, and my thoughts.
I sometimes wonder if it's unhealthy, if I'm bottling up masses of hostility, resentment, and hopelessness that will one day hit me all at once. Why else would it be that some people cry in situations where I would simply be still? But I don't feel any internal tension. I feel overwhelmingly peaceful.
