So now, especially now, I have to say that when you suspect someone of playing games, or being shady… your hunch is almost always right.
Therefore always investigate further.
No matter how much the other person complains and tries to make you the bad person for being “annoying”… always investigate why you suddenly have a bad feeling.
Who knows… your story’s antagonist may be committing an illegal crime against you right behind your back. And while all bad acts eventually get caught… wouldn’t it be nice if they could get caught sooner than later?
So yeah… life tip #739927373: investigate all doubts and (bad) hunches
