I'm similar to Mobius, I empathize so readily that other people's emotions are contagious for me. Generally if someone else is crying I will find it very hard or impossible not to cry (sometimes even when it's a little kid, it all depends on how they sound and whether they're being adequately cared for by nearby adults). When there's a crisis I can put my emotions aside but it's like they're a ticking time bomb that might blow at an unknown moment. I certainly couldn't make it all day, and even if I could, what a nightmare for the people I'd come home to.
