(ebayer said he'd include instructions).
Maybe he didn't include them so you'd go ahead and try it anyway and then if it didn't work he could say that you did it wrong and didn't wait for him to send the instructions because he obviously was going to send the instructions soon after realizing that he "forgot" to send them or obviously made a mistake and that you should have emailed him about the "missing" instructions. That is to say, maybe it was already broken and he was hoping to trick you into thinking that you broke it yourself.
