Hi . Bob ! We've been working hard at our lessons for a fortnight . So why don't we take it easy this weekend ?   Okay ! What do you suggest ?   How about seeing a play ? I hear Hamlet is on at the National Theater .   Is that so ? Why not ?   ( looking at a newspaper ) Oh , dear me ! There's no performance at the National theater this weekend . So we have to go to cinema instead .   What's on ?
