In class 12, I was secretly talking to a girl from another section. Since school relationships became instant gossip, we told almost nobody.
One day, I sent my best friend a screenshot of our chat because I wanted advice. He forwarded it to another friend without asking me, and within two days, half the school knew. The screenshot eventually reached her cousin, who studied in the same school.
She stopped talking to me because she felt I had exposed something private. I blamed my friend, but deep down I knew I was the one who took the screenshot first. That incident taught me a lesson I still follow: private conversations should remain private, even when you trust the person you are sharing them with.
