Never underestimate what someone can do to your life, given enough time, and left unchecked. You may be minding your own business, just doing your thing for years even decades and come to find out there was someone setting you up.

Instead of getting angry and potentially making the situation worse, just keep working hard and continue until you reach a level where highschool type peoples are no longer in your life. I see alot of them, they hang around the same people they did in highschool even into their late 30's

You should feel sorry for that mentally ill person who has nothing better to do. Just keep doing your thing.
