Um...hello?

I'd like to remind people that humans, for the most part, are generally fairly solid.
If you are walking along, particularly if you are pushing a pushchair or wheeling a bike, and someone is in front of you, or if you are opening a door that clearly has a person in front of it, you are very likely to collide with their mass.

I don't know if your day is fraught with will o' the wisps or you "see dead people" but for the most part you can assume the people you see are not ghosts or side effects of your mental illness. This being so you should probably formulate a plan to not walk directly into them as if you expected to pass right through them.

I'm not talking about the reasonably normal state where you turn and walk into someone by accident or didn't see them the other side of the door and so on, everyone does that, I'm talking specifically to those people who look right at you and still decide to just keep going, the same people who must be fighting the urges of the voices in their heads that tell them to "burn them all".

If you do ignore this advice could you at least try not to make matters worse by looking at the person you just walked into, the person you chose to collide with, as if they were a disgusting peon for insisting on existing. You did it. They were minding their own business.

I've seen people actually change the direction they were going in to make sure it intercepts someone else's path. To walk across a lane of pedestrians rather than with the stream, and still act like they didn't do anything and it's all your fault.

Wake up idiots! Everyone has the same rights when it comes to walking around town. You don't get to barge and slam into people or trip them with your crap just because you have an inflated ego.
