My girlfriend has gotten mad about this in the past. I'm like hold the run button then press the jump button. She would get angry and tell me to say which buttons those are. I would really have to think about it, when playing a game I associate a button with the function and forget which button is what.
I don't know hold on! Pretends controller is in hand. Presses thumb hmmm left and down. Okay what console is this? Square and x? X and A? Whatever the hell Nintendo is?
