Are you credulous?

When I was young I usually assumed everyone was telling the truth, but experiences in real life, in AOL chatrooms, forum sites, etc. have made me less trusting. If what someone is telling me is pretty straightforward and common (e.g. “I’m from Cleveland”) I assume it to be true, but when stories seem the least bit larger than life, mainly online, I automatically assume they are lying. I’m not about to call anyone out on this or make a big deal out of it, so no one is the worse for it, but inside I believe them to be liars. Do you think most of the stories you hear from people on the internet are true or false? What does this say about us? Does it matter if I think someone is lying if I don’t tell them or anyone else I think it?
