So you have a problem with people pulling a prank, but no problem with lying about a person performing a criminal act?
That's strange.
Whats false? do I know you? do I know why you are coming up behind me? I"m from the east coast someone I don't know is coming up behind me toward me you darn well better believe I think they are after my purse. You invade my personal space you better believe I"m defending it.
No false statement there, No never met this person before, caught them out of the corner of my eye coming toward us , thought they were going to grab my purse or camera and I reacted.
every action has a consequence don't like what could happen to you don't pull the prank. There are no guarantees in life.
