 Person1:      I love going to art galleries , particularly when one is holding an exhibition of abstract art .  
 Person2:  I never understand the meaning of those painting . They are too abstract for me . I didn ’ t pay much attention in art class at school .  
 Person1:      Art isn ’ t for everyone . I ’ m going to an exhibition tomorrow at the national gallery . It ’ s an exhibition of greek and roman sculpture .  
 Person2:  I like sculpture , especially that form ancient rome or Greece . What time are you thinking of going ? I ’ d love to go with you .  
 Person1:      I thought I ’ d have an early lunch and go immediately afterwards . Does that sound ok to you ? Bus 51 goes directly there .  
 Person2:  That sounds fine . What time shall we meet at the bus stop ?  
 Person1:      Let ’ s meet at 12:30 . it will probably take us there or four hours to see all of the exhibits .
