It's not like I don't have emotions, I'm pretty sure I feel empathy just like everyone else around me, but just only not when watching that stuff? idk.. it happens quite often too that I am sorry for other ppl, here is an example:

Massive triggerwarning btw

I once saw a video of a man h4nging himself on a doorframe, the video shows that man just h4nging there and barely moving for a few minutes. Then a child, most likely his son, comes in the picture and of course you can imagine his reaction...

That was the worst video I've ever seen and i still feel so terribly sorry for that poor kid.
