I would not try to convince anyone to use bitcoin or the opposite. What I would do would be to explain what bitcoin is, how it works, its applications in the real world to this day and future expectations. If they are interested then I would explain more in detail, how to get a wallet, how to send and receive funds, etc. Once they had their wallet, I would lend them some funds to try for themselves. I would never recommend going to the faucets because they would get bored. Anyway I think over time you will not have to go tell anyone about bitcoin but it will be the other way around. As it becomes more popular and known, people will come and ask us about "that thing you do with the PC".
I agree with you because no need to explain or tell about bitcoin will come a time when people will ask how to earn money just by playing computer.
