I just figured she was a raging alcoholic

Harry Dunne: I don't get it, Lloyd. She told me ten o' clock, sharp! Are you sure you went to the right bar?

Harry Dunne: Yep. I'm pretty sure. Lobby bar right by the lobby.
[sighs]
Harry Dunne: Maybe she just had a change of heart.
Harry Dunne: Oh, that pisses me off! That pisses me right off! I hate when women do that. She wanted to see you again! And now no? Now… Wait a minute! 

Wait! She must have meant ten o' clock at night!
Harry Dunne: Do you think…?
Harry Dunne: Why would she have you meet her in a bar at ten in the morning?
Harry Dunne: I just figured she was a raging alcoholic.
