Overview
One of your friends might have an interesting social opportunity for you, but you need to do some research on your own before signing on or committing yourself in any way to it. If your friend is truly a friend, they won't mind in the least if you do your due diligence before associating yourself with their little scheme. And if they get defensive about it, then you know for sure that something is up! You can afford to be honest and open up to this person about your concerns.
