Provide the theme summaries for the following conversation: 

Lupa: Risk Management, know anything about it? :)
Martha: Yeah, I had it as one of my electives last year.
Lupa: Was it hard?
Martha: Umm... let's say, boring :)
Lupa: Hmm... I've already selected it, and I can't opt out now. Did you have to study a lot, though?
Martha: Not really. We had a great teacher. He explained things really well in class, so it was quite comprehensible :)
Lupa: I wonder who I'll get. Do you think male teachers are better?
Martha: In business courses or overall?
Lupa: Overall.
Martha: I don't know, it depends whether they're dreamy or not :) Just kidding! It really depends on the subject.
Lupa: Which book did you have?
Martha: I couldn't tell you the name of it; it's all in the past and long forgotten. If I find it, I'll send you a pic.
Lupa: Ok, thanks. See you next week.
Martha: Take care
Lupa: Oh wait, there's something I've been meaning to ask you.
Martha: Ok
Lupa: We have to meet in person for me to explain it all. We'll talk later, bye.
