People throwing thrash on the way usually is a sign of not enough trash cans in an area.

No. I regularly see trash on the ground with sometimes as much as 5 trash cans in sight that are less than 20m away.

If you cut yourself with a knife, it might be your fault. And it might be that the knife is sharp on both sides and has no handle.

It feels like I’m thirty years too young to get these jokes.
