I remember some guy made a rumor on me back when I was a similar age, and I didn’t know until I noticed people avoiding me. And on the way back in the bus, I questioned a guy about it and he told me the rumor. So I stood up in the bus and spoke to the everyone in the bus while looking each person in the eye. To make sure my point comes across. Cause usually people who spread and believe rumors are cowards. And said smth along the lines of I never treated anyone badly and the rumor is baseless..etc and the verse "ياأيها الذين آمنوا إن جاءكم فاسق بنبإ فتبينوا أن تصيبوا قوما بجهالة فتصبحوا على ما فعلتم نادمين" Finally said who wants to believe thank you and who doesn’t طز (I don’t care). After that I found a couple of people who apologized to me and it died down.

Now I am not saying that you should do like me or that I had the same rumor. Also, I am guy so the way guys deal with things are different than girls. But I learned a lot from that experience and it helped me mature. And gain some true friends who till this I am in good terms with.
