Mike , I'm afraid I can't come back home for dinner tonight .   Not back home for dinner again ? That's the third time this week !   I'm sorry . Our company has just opened . There are always too many things to handle . You know that .   You don't have to explain . Suit yourself .   Please forgive me . You have my word . I'll spend some time with you on the weekend . I promise .   We'll see .   Thank you for understanding . I promise I'll make it up to you .
