I am so so bad when it comes to crying over movies, haha. Or at least tearing up even if not actual crying. Even for scenes that aren't that bad, sometimes I'll feel my eyes start to water up and I'll be like "dude, self, no, don't even think about it". And then if it's an actual emotional scene? Whoops there I go, forget it. Then there's a scramble to make sure I'm not seen crying at all because that's just embarrassing. :')
Aside from that, I tend to cry mostly if I'm in a bad mood, whether it's because of sadness or frustration. I think frustration is a bigger trigger for that than sadness is, actually - I have to be really down for sadness to get me crying, but the downside to that case is that I tend to cry for longer. But frustration...yeah. There are times when I experience that badly enough that I will actually look to go make myself cry because I absolutely need that release.
Last time I cried was over a song I was shown the other day. I can't even properly describe what happened, just that it tweaked my emotions in some way and yep there I went oh boy. And then I went to go listen to it several times more. Yep.
