The same old lady poured orange juice into a thermol(dunno hw spell -.-'') flask cos she was gonna go picnic with her frens . she went onto the double decker bus with her frens. the 1st deck was crowded so she went to the 2nd deck . when the bus reached the destination , they did head count and one was missing . they found the old lady at the 2nd deck shivering and sweating . her face was pale . WHY?
