I've looked back and remembered the pets I've lost and even today, (right now as fact) my eyes tear up. I've been hurt lately with my ex deciding it's time for her to leave and us to split, I've lost relatives recently, my father last year.
I will disagree to a point, it does help to soothes the soul to cry, my soul anyway, to quote B-Tribe, "You won't see me cry..." but it sure feels like something is being removed, lifted, pulled, or I'm being otherwise exonerated of whatever guilt and pain that may have been attached.
Though sometimes a bottle of wine is involved, it's what it usually takes to get me started, but I feel it as a worthy exorcize of my psyche on occasion.
