Thank you all, Folks !!
It was all in good fun as I was having a lazy boring day and was twiddling my thumbs as to what to do next !!
I will try and find a better riddle next time !
What if the question suggests he stayed five full consecutive days .He arrives on Friday say 5 in the evening not a full day and leaves on the following Friday at 9 in the morning .Or else he as not THE lone ranger but just any old lone ranger and had a horse called Friday .
