If someone could point me to a twitter type answer that would inform and twig their curiosity, i think it would be a better outcome.
Definitely will tell him to google it and after that, I will explain the basic to at least trigger his interest. I believe information on the site is much precise than what we will explain to them. Since most of us is not a programmer, nor know the whole information about Bitcoin (majority here just know how to send and receive bitcoin from a third site, I have met people who do not know how to create a wallet in electrum) it is best to advise them to search what Bitcoin is. It saves us a lot of time and the one looking for an answer will have a robust source of information.
