Tina: Hello Mrs. Jones. I'm really sorry, but my timetable at uni has changed and I won't be able to come on Thursdays any more.
Karen: Oh, that's not good Tina. Is there any chance it will change again or maybe you could change it somehow?
Tina: I'm afraid not, I already spoke to my supervisor and there's nothing they can do.
Karen: Hm, we need to make it work. Kids really like you.
Tina: It's nice to hear Mrs. Jones. I like them as well and would like to keep working for you.
Tina: <file_other>
Tina: Here's my new timetable. I think it shouldn't change until the end of the semester.
Karen: Thank you Tina.
Karen: I see that you have Wednesdays off. I think we can make it work. Let me consult it with my husband first
Tina: I understand. I have less classes this semester, so I can also come for the evenings as well.
Karen: That would be wonderful. Do you know anyone who may help us out on Thursdays?
Tina: Hm, I'll talk to my friends at uni, I think it won't be a problem.
Karen: Great, please let me know when you find someone. I'd happily meet them, just in case.
Tina: I understand, I'll let you know as soon as I find someone.
Tina won't be able to come on Thursdays any more, because her timetable has changed. Karen still wants Tina to teach her children. Tina can come in the evenings. Tina will look for someone willing to teach Karen's children on Thursdays.
