A childhood belief about i'm different

When I was in second grade, my best friend lied a lot, and one day he told me that he had a motorcycle. I asked if he would come and pick me up on it, and he said he would. I spent all afternoon looking out the window for him, until my parents finally told me he was lying. The next day he said him mom wouldn't let him come get me, but from then on, I never believed him when he said stuff like that.
