Give them some.
Yes after you teach someone or say anthing about bitcoin. Give them some for them to try that all what you've said is real.
Just like how the saying goes, "Give a man a fish, and he'll live for one day. Teach someone to fish, then he'll live for the rest of his life." Just like in bitcoins, if you give someone some coins, they might just spend it on gambling or some ponzi investment sites out there. If you teach him how to make coins, then he'll carry on having more and more coins.
All I'm saying is that you have to guide him/her after giving some coins. Might as well don't give him/her any coin because it probably will just end up being invested in some scam sites. We all been on that stage. We all thought that they would really pay us. But unfortunately, they don't pay at all.
If you regularly spend time with them doing earning bitcoin, then one day they'll become as good as you do. That's how you properly teach someone about bitcoin -- doing it on a regular basis, checking up on them from time to time.
