the cleverness of crazy guy

fun and joke african civilizationhello dearest how do you do? Guess well Today by 08 AM by 08:00AM I get a rendez-vous with Tintin to the nearest crossroad of JACKO. I mean the dwelling of the mad man. So he was strolling around the place. Once I came he told me my friend "you are late how could it be possible? .what time is it? As he asked I looked to my wrist without seeing it. So I replied "I don't see my watch " .He did the same by checking his wrist. As we didn't both see what time was it , we decided to ask a mad man who was strolling around the place. Tintin said please "could you please tell me the time ".the mad man said "OK let me do it ".he put a stick and pushed It in the ground. And then put a measure of the shadow cast by the stick. After he looked the position of the sun .then the mad man said "it must have been quater past eight 08:15 ".so we feel daze and impressed cause I remember that I got a watch in my pocket . So I checked the watch and saw that it was twenty past eight 08:20.i said "wahooo how could it be possible ".tintin also seemed to be very impressed. But tintin asked "if it is a cloud day and your stick could not cast shadows how would you know the time "the mad man said "in that case I would look to my watch
