I haven't paid it much thought before, but I've a bunch of people who have told me flat-out lies, usually relating to my interests.
When I was five, I had a friend lie to me about seeing a new Thomas the Tank Engine video that I hadn't seen.
When I was seven, my cousin made up stories about Mario games, including a new game that was coming out (which I called him out on for a factual discrepancy, although eventually I caved).
When I was twelve, I had a friend who had told me about an exclusive Star Wars CD, a trailer for this really outrageous movie that didn't actually exist, and a cutaway lightsaber prop (the last of which I called him out on eventually).
I've had a friend for several years who has told me some Star Wars-related myths and as recently as a few years ago told me about an "exclusive" demo he saw for Nintendo DS (which I was quick to point out was not true, although for some reason I tried to rationalize it to justify that he wasn't telling me the whole truth).
Is there a reason people have acted like this to me? Do lots of people do this, or have I always been just enough of a loser for them to get away with lying to me?
