What's up ?   Nothing much , what's going on ?   I'm having a party this Friday .   Oh , really ? That's nice .   I wanted to see if you wanted to come .   This Friday ? Sorry , I already have plans .   Doing what ?   I'm going to dinner with my family .   I really wanted you to come , but I understand .   Yeah , maybe next time .   I'll hold you to that .   Sounds like a plan .
