That's how it is suppose to be, I don't it is right to just see anyone and start talking about bitcoin with the person , even if the person is someone you know very well. Before making any conversation about bitcoin with anybody you need to be sure if the person has same interest of bitcoin just like you and  it will make the conversation to go very smoothly without any rejection. Having discussion with the wrong people who don't care about bitcoin and understand it, you may even be seen as a suspect of scam maybe based on the wrong investment they may have encountered even before now.
