What should be a dialog of a florist?

Answer 1

Writing dialogue is not as hard as you're letting it seem. You have dialogue all the time -- it's called talking. If you honestly cannot think of what your characters are going to say to one another, you need to go take a break and go somewhere out in public. Sit somewhere in the middle of a crowd for one to two hours and just listen to people talking. Then, go home and write down some of the things you heard people saying. That's dialogue.

If you don't know what a florist would say, you need to go to a florist shop and pay attention to what sorts of things they'd tell or ask their customers.

When you need to have your characters talk, just pretend it's you and a friend (or several friends), and have them say something you'd probably say in the same situation. Then imagine what your friends would say in reply, and go back and forth that way. As you become a better writer, your characters themselves will "tell" you what they want to say, because they become like real people to you.
