Example Input: ;,F: Amelia, what in particular do you have to do as a wedding planner?

M;,F: So, do people ask you to organize their weddings to save money? M;,F: Well, I reduce some of the costs. But they have to pay my fee, so it works out about the same. In most cases, they are simply too busy to do it without assistance. M;,F: Tell me, what made you want to become a wedding planner? M;,F: In my case, it was after I'd been doing some voluntary work for a non-profit organization. Others come into wedding planning through different routes, such as restaurant management or providing meals for open air events. M;,F: So how could someone find work in this type of business?
