How about if your essay reader really needs to go to the loo really bad, but wants to finish the current application they are working on and they are thinking they really want to give you a ‘4’, but then, they get to thinking that it would be unfair and selfish if they gave you a ‘4’ just because they were trying to finish to go to the bathroom, so instead, they give you ‘5’, and Voila!
Is that “luck”?
