For me, it is always when someone asks me a question which answer could easily have been retrieved through their phone online. You’re meaning to tell me, that what you have in your pocket, is not some form of gateway to information that can answer anything you’re curious about at just about anywhere?
So you go and bother me instead, whom for all I care, could just lie to you or to be honest, admit that I don’t know everything. Because that’s what your god damn phone is for now and has been for a while now. Go use it, stop nagging me, I know when to use it when I want to know something, I don’t go around bugging people and asking stupid questions.
Not to justify littering in the slightest (it’s gross and I don’t do it) but I think I can give you an insight in some of the thinking. Because in my own home, I frequently and unthinkingly ‘litter’ even though it annoys me! I open an envelope and read the letter, unconsciously dropping the envelope on the floor. I constantly find empty food packaging in weird places because as soon as I’m done with it I just drop it.
Fortunately I don’t do this in public because I’m always more aware of my actions when I’m out of my own space. But within my home, if I’m doing something while focusing on something else I’m prone to abandoning things carelessly, and when I find them latter I’ll be mad at having to tidy up after myself. So, maybe some folks are like that in public? Also, some folks consciously and shamelessly litter, and there’s really no excuse.
So… Do a lot of people do this? I can’t imagine just letting things drop willy nilly that I am handling. I place the envelop on a table and after reading will either dispose of it all, put the letter back in the envelope and place it somewhere specific, put the letter somewhere specific and dispose of the envelope.
