I don’t know about everything. “Most everything I say on the internet I believe.” Yeah, I’ll go with that.
I just kind of assume that sooner or later, I’ll forget some of the stuff I’ve posted, but my name will still be attached to it, so it’s best to mean it or surely someone will drag some forgotten thing from a forgotten corner of the internet into the light and ask, “Did/Do you truly believe ‘this’ thing over here we dug up that you said?” And who wants to say, “No, I lied.” I don’t.
