how about 4) while yapping to the one person who listens to you yap while you're driving so you can't write it down (the European mind cannot comprehend this.)
having really really good dialogue for your story but it’s either 1) in your bed in the middle of the night or 2) in the bathroom shower, so you have to wait about fifteen minutes before you can get to your notebook to jot down the ideas but by then it has dissipated and so has your entire sense of being in this universe *screeches in disintegrated*
