Guided my 65-year-old father through installing Linux Mint on his laptop—entirely over a WhatsApp video call.

We live in different countries and Windows was getting on his nerve so much so that he asked me for an alternative and I'd recommended Linux Mint, he's never installed an OS in his life but I was able to guide him over WhatsApp Video Call, everything from downloading ISO to Creating Bootable USB to Installing and Setup. Mighty impressed I am. :)
