A conniving person asks all the right questions to use every answer. They search for the opportunity in the weakness of others. They seldom associate with someone if there is no self-gain. Every chance they get to use you, they will. They look for opportunity in the weakness of others. Everything they do has a reason or motives. What you say, can and will be used against you for future gain.
From My Heart: A conniving person sees the outcome of a thing before it begins. They see the gain and how to avoid the lost. Every point is covered and every plan carefully thought out. Even in their lost, they gain. Conniving people are careful with their words and actions. They fill their glass up from top to bottom but they see it full before you even starting pouring.
