the crazy way rumors get started

Sunday i get a message from my best friend and another one of my friends. They both are asking me am I pregnant and I'm like no where did you hear that from? They both say from this guy and he randomly brought my name up and said "raven pregnant because she told me not to squeeze her stomach". I went off because that makes absolutely no since to figure that I'm pregnant. Also why are you bringing my name up in a conversation that I had nothing to do with. An even if I was pregnant which I'm not I don't need him going around telling my business that I would never discuss with him. So I messaged him saying I'm mad at you and he asks why, and I say why a is my friends messaging me asking me if I'm pregnant. He tells me he only said it as a joke because he was telling them how we play fight on the bus. I told him why is my name being brought up in you all's conversations and they both said the same thing and you weren't playing according to them. He got mad at me saying i can believe who i want and some other crap but they both said the exact same thing and you shouldn't have said it.That was just how crazy and easy rumors get started and i was completely clueless about it.I absolutely hate people who bring up my name and start saying stuff about me all my life I've never had a rumor spread about me and i don't want to start now. I don't do things with people or anything and i don't mess with the wrong so i took pride in keeping my name clear and i don need that little thing to mess that up!
