Why do people spread rumors about people who did nothing to them?

I look like im f*cking pregnant… And have for like a year… Im not… In 8th grade, and people spread rumors that I was pregnant, it ruined my year.. Because they never shut up.

So I started ignoring people…

Then his last year in 9th grade, some stupid b*tch starts telling people in my seminar class im pregnant. And everyones comeing up to me asking if I am… And a few wouldnt even ask if I was, and just straight up asked who the dad was.

8th grade is one thing.. There all stupid and immature… But you think the transition from middle school to highschool would make you grow up a little… Instead it got worse.

They told everyone!

They even told my counselor! And asked what I was going to do with it!

And im not even pregnant!

I just seriously look like I am…

Thats not even the worst part…

In 8th grade, I slept with the guy scott (if uve read my other questions, you know who he is)

Then when we went back to school , he noticed I looked pregnant. And asked me if I was… And I said no, and he said he knew I was. And I said I wasnt… And thru out the next few weeks… He kept passing me notes with a stick figure that was suposed to be me with a baby in a circle and pointed at it saying “my baby”

And always reached around my chair and put his hand on my belly. And would say “oh! I felt it kick!” and I would get so mad… And he would say it so loud.. Which never helped my pregnant rumors!

What do people gain from making peoples lives miserable?
