I was wondering why do rooster crow everyhour at night. Sometimes, when observing them, they are better than my watch. From among the mylot friends, is there anyone who can compute the time at any moment without the aid of a clock. Dont you wonder? If you have any idea, will you share and I will tell you mine after a while. Just for laughs.
