For example, if some bad looking guys came walking in my direction.
If I said to them, "In order not to trip you should walk rather than run."
However, for some reason after the other side realizes it they disappear somewhere in the hall.
Occasionally there's a guy who suddenly looks out the window and says, "The weather outside sure is good today."
Even though it's raining.
I thought "I'm lucky for them to not pick fights".
I couldn't have possibly imagined that the other side thought that as well...
