According¹ to his mother,Roger is a careless person.He always forgets something else while he's doing something although he denies² it.He insists that he's careful,but he's simply unlucky.So he gets into trouble everyday.

Yesterday was an unlucky day,according to him.After a day's work,he felt tired and came to a park near his home to enjoy the quietness here.He bought a newspaper at the newsstand,and then seeing an empty bench across the path,he came up and wanted to read his newspaper there.He did look at the bench for a while to see whether it was clean.But he didn't notice the sign behind the bench which says"WET PAINT".He sat there reading the newspaper for a few minutes,then left for home feeling much satisfied³ that nothing unhappy had happened to him that day.People behind him were laughing at the painted stripes⁴ on his clothes.
