I can't even remember the last time I raged this much.
Playing IaMP with Yuyuko, it's going well until Suika. The different timing during the second Spellcard throws me off completely and I get stomped on (literally). During the third Spellcard, my controller stops working, because I hate wireless hardware, that's why. I can't even pause the game because I'm playing on my laptop which has only two USB-slots. Since it's connected to my monitor, I keep the laptop shut and, having to plug in the controller, I unplugged the keyboard. Didn't think far enough to use the laptop's keyboard, but the controller started working again after some time. Then, during the last Spellcard, I notice that I don't know any attacks from below I can use with Yuyuko, so I wind up losing, having gone into the battle almost untouched.
I was desperately trying to vent my rage, but deep down I knew that I couldn't destroy the controller, lest I reduce its value. I eventually decided that stomping on my bed would be a preferable course of action, destroying some of its inner frame in the process. My sister telling me to "grow up" and that "it's just a game" didn't help matters either, but fortunately, I had already calmed down enough to politely explain that I may have lost my temper a little.
Truth be told, it was unsightly and I am ashamed of myself.
Edit: Now I feel like I can move on with my life, gave it another go and destroyed Suika. Good thing, last time, I didn't have enough resources to gather the courage to try jump-attacks, even though I had used them before.
