It's not that I automatically assume that everything he says is true, but I haven't seen anything that I immediately know is a lie. (Like the recent tent video. That thing jumped out & screamed "FAKE!") I usually believe that people are being honest unless they obviously aren't. Sure I can get disappointed occasionally, but life is too short to waste it being skeptical of stuff that doesn't matter.
The little BF kids are always carrying toys around with them that they pick up here & there. Why couldn't the "fish eye" be an eye on one of the toys? I've heard some of them talking off in the distance & they didn't sound all that different than Mike's buddy. They might have sounded even more like him if they had been speaking an unfamiliar language.
So, I'm willing to believe him until he's proven to be a hoaxer, & that hasn't happened yet.
