I cry at the oddest times.  Some time, some things that should make me cry, don't, and things that other people aren't crying about, do.
When I really get going, I can cry for hours.  On 9/11, for instance, when I got home and started watching TV, I cried until I thought I didn't have a drop of liquid in my body. 
When Nik Wallenda walked over the Grand Canyon on a high wire, I cried the whole time.  The Spousal Equivalent thought I was nuts.....but then he mists up when those animal charities ads come on TV with the sad-looking dogs, so I don't think he has anything to chide me about....y'know?
Music makes me cry.  Movies make me cry.  I don't cry at funerals.
