Hi , charlie , are you busy this evening ?   Sorry , I'm afraid that I've got plans tonight .   What are you doing ?   I'm going to my parents ' house for my father's birthday .   How old is he today ?   It's his 50th birthday .   Well , wish him a happy birthday for me .   Sure thing . What are your plans for the evening ?   I was just thinking of going to a movie tonight .   Well , if you can wait until tomorrow night , I'll go with you then .   Sorry , I've got people coming over tomorrow night .   Sounds like this weekend just isn't going to work out for us .   Sounds that way . Maybe some other time then ?   Sure.Hey , I'm sorry , but I've got to get going .
