Watch  

A 8 years old boy received a nice watch for his birthday. He focus  on the watch only. He read the time almost each two minutes and said : ten after eight  ( 8:10 ), eleven thirty ( 11:30 ) etc... When he said twelve O'clock his uncle told him that you can say twelve O'clock or noon. When the boy saw twelve after twelve ( 12:12 )  he said uncle look, look, now the time is noon noon.
