I agree largely about yoyoing and Norwich seem to show how it's done up to now,but I don't think it takes too much to be Knocked off course by something of an adverse nature.
Well I mean, who hasn't woken up to a damp mattress at least once in their life, or had to find the porter to let you back in ,after opening the wrong door in your grundies or less as it slams shut behind you , standing in the corridor.🙄😟
