Hello , Bobby , It seems that I can't arrive at your home by 12 o'clock .   What happened ? We're all expecting you , Hans , Dick , Archie ...   I'm so sorry , I've been held up by the damn traffic jam for half an hour . I'd have arrived but for that .   I see . Where are you now , Li ?   Thirty meters ahead is the Waterloo Bridge .   It's not far away from home , It's - let me see – about 20 minutes'walk , Can you walk here ?   I've thought of that , but what can I do with my car ? If only I had taken a taxi !   That's too bad , But don't worry.We ' ll put off dinner till one o'clock .   I'm so terribly sorry to keep you waiting .
