I sure cry. Lots of tears, but rather silently. "Sad" is too blunt a reason, so I haven't voted. When I was much younger, I watched Captains Courageous - and did I cry!! Being more sensitive then to other people's reactions, I was glad that the theatre was dark.
Now comes the interesting part, I think. In the last not very many years, I cry aka weep a lot. Sometimes, it is sufficient that I read in the morning paper of a puppy that got its tail caught in a door. I find it difficult to clear my eyes when reading of disasters. I was more positive to Pope John Paul II when he was new in the business, but despite his later conservatism my eyes are filled with tears when reading of his last days.
There may be (at least) two reasons that I'm rather over-sensitive now. The physiological explanation: my brain infarction as a result of my stroke may have hit a restraining centre. I sometimes say that it hit a centre for social restraint. Nowadays, I find it immensely easier to get friends, communicate with strangers etc.
The psychological explanation is that I was so hard hit by my (and my then fiancée's) dog, an absolutely lovely Red (aka Irish) Setter girl, just over one year of age, acquiring an incurable auto-immune disease. I was hit so hard that I developed a case of herpes zoster, and for several years, I couldn't discuss her with anybody: relatives, friends, physicians, psychologists, without bursting into tears. So if you find misspellings in this post, you know why. That experience might very well have made me more sensitive as well as moer empathetic.
Please note that I'm not complaining. I think that those experiences (and a few others) have helped me to live a more enjoyable life than ever before. I as well as the people around me feel that I'm a human being, not a robot of sorts, and I sure am now more open to other people's feelings and needs, and I try to be pre-emptively helpful to people I know and care for. Finally having arrived at atheism, I can't rely on any one book or whatever to tell me what to do and how to behave, so I have to develop a consistent set of ethics of my own with which I can live in a way that's acceptable to me as well as to my environment and applicable laws and regulations (heck, that last part was a case of a technical translator's occupational disease). Not to be suspected of proselytizing, I won't elaborate on that angle.
