It took about a week.
A full week to convince my mother that I hadn't gone mad and didn't do drugs and stuff.
They desperately wanted me to go to a psychiatrist and all that but I clearly indicated- I'd punch anyone who'd bother to lecture me about mental health and all that. I had to extensively explain that this red iris was just normal- it was not though. And why did I still have red eyes despite not having any healing powers? Like what the hell!
I didn't tell them about the other world.
Rather, I made up a story about how I got swept away in a third-world country and got lost there. I walked with the farmers, lived with them, helped them through thick and thin, and when I made enough money came back; this red eye was just a product of contracting a rare mutation that was totally harmless.
