How do you find out if someone is telling you the truth?

People lie all the time! Is it really a bad thing though? Do we even want to know the truth half the time? I feel like most of the times that I have weaseled the truth out of someone I was much less satisfied than I should have been. The truth is good so much of the time as well though, we seek it out for more purposes than that we simply do not like being lied to. The truth can be enlightening, it can lift burdens off ourselves.

Yet, still how do we know if we are actually receiving the truth? We seem to be lied to on a daily basis, by the government, by our parents, by our friends, by the cafeteria workers even! I think finding out if someone is being truthful with you is a near impossible thing to do. How do you interrogate someone about whether they are lying to you without offending them? You almost cant, so I think there is no easy way to determine if someone is lying to you, it is just something you have to decide whether or not you really want to know the truth and at what cost it may come at.
