Getting mad after losing live, yet not caring when online

[Joshssj4]

So today I played a live home game with some really truly awful players, 1/2 uncapped buyin. I lost it all after a horrid suckout and blew 80$, keep in mind i gave 30$ to a friend after he busted. So anyways, after it was over I was absolutely furious, going crazy in my mind, which brings up this question. Why do I get so mad blowing 80$ live, yet barely mad about getting sucked out of a 400$ pot online.
Any input?
