  Carmen: Sure, it’s 555 154 124, but he is at gym now so try a little bit later.
  Nina: Thank u very much. I hope he will have some free time.
  Carmen: You must ask him, I don’t know.
  Nina: Of course, I’ll try to call him later. 
  Carmen: He should be at home about 8 pm.
  Nina: And what about your exam?
  Carmen: Quite good but I have a lot of tasks to do. It’s sometimes hard not to forget some dates.
  Nina: I have great book about the II WW. I’ll give it to Rick for you.
  Carmen: Thx, It will be helpful cause history is not my best side 
  Nina: Like math for me 
  Carmen: 
  Nina: Thank u for help, Have a nice evening with my bro!
  Carmen: Thx!
target: Nina needs help with maths. Her brother Rick recommended contacting Carmen. Carmen's brother is good at maths and she gives Nina his phone number. Nina should call him in the evening, after his gym activity. Carmen's exam was good, but she forgets dates. Nina offers her a book about WW II.
