I also did it some time ago where I showed two of my classmates my bitcoin wallet then the amount inside it as well as its price in my local currency and as usual they get curious too and asked how is it considered as a money or how it can used to buy some stuffs and how can I convert it into cash . I explained to them how can bitcoin works and how it can be used as a medium of exchange or payment, why it has a value and lastly how am I earning it .
Some what we had the same way on how i spread bitcoin, the only difference was that i asked them first if they heard about bitcoin after that i give them a little discussion and when i saw in their faces that still they are confused or not interested i let them show my wallet also i told them how it works in the forum then that's the time i saw their faces got intersted so that's the way i introduced bitcoin to my friends.
