Florean & Marlene
"I couldn't agree with you more," Florean said in response to being upfront, and while he knew he was being hypocritical, he judicially decided to not be upfront with Marlene and tell her that he liked her and thought she was pretty. There was a fine line between being upfront and being creepy. Telling a woman you just met that was probably crossing the line.
"I'm not following the guided tour," Florean told her. "The guides usually skip a bunch of information to make it quick, and I find they get annoyed when I interject with information I think is too interesting to keep to myself." The same thing happened when he attended Professor Binns' class at Hogwarts. "I was heading for the Asian exhibit, have you gone there already? But yes, drinks first!"
They began wandering toward the bar. "Stables? Do you ride? You mentioned Nearly Headless Nick... were you in Gryffindor? I was in Hufflepuff."
