I have a few times.
Years ago at a Spanish restaurant the entertainment was a guitarist who played both FLAMENCO and CLASSICAL guitar. There was one song he played, the name of which I do not remember, that brought me to tears. I can't remember ever hearing anything so beautiful as that.
Another time when I saw the Movie HACHI for the first time. I was inconsolable and cried my eyes out. I've seen it a few times and each time I cry.
Other times I've gotten glassy-eyed. A double rainbow...a beautiful sunset...seeing a loved one whom I hadn't seen for a long time. You know. You've been there too haven't you?
