Tears of ?

It's weird how sometimes I'll be sitting here and a tear or two will fall for no apparent reason.  I don't feel depressed as I understand it, nor joyful.  Just "meh".
Nothing "feels" wrong.  I'm just experiencing my night, doing whatever it is I'm doing.  In this case I'm sitting here playing WOW listening to various genre's of music.  Some upbeat some not.  Just a random YT stream mix.
The human body is so strange.
Nobody will probably see thsi till after I'm gone but I'm not sure that I put it here for others to see but instead just to document my feelings/thoughts so that if someday someone wants to know more about "Bear" they will know.
