I'm thinking of when I was in high school senior year and I told people I was dropping out to see who actually believed in me and who made fun of me. I learned people would make fun of you the second they think that you have failed. A couple months later they learned I was actually accepted to an ivy league.
What happened after you learned who your fellow students really were.
I'm still bitter toward those teenage jerks who made fun of me and still wished that they fail their final exams.
You should not lie about dropping out. I know that you were just trying to see what you happen, but it is still not good to lie.
I just needed to know their true colors.
There is still no excuse for lying to your classmates even if you did it to see how they would react if they thought that you had failed out. Don't play with people unless you are looking for other people to play you one day.
