Appoint you 2/3 days in advance
This is a sincere one. At the beginning, it indicates that he had planned to date you earlier. At least, it also indicates that he has considerable social courtesy.
Make a temporary appointment with you on the same day
This man may just be feeling lonely for a while. If you happen to be lonely and don't mind the consequences of dry wood hitting the flames, then go ahead and keep the appointment.
He said he wants to bring his good friend and ask you to bring him too
When encountering this situation, it depends on the man's personality: if the man is honest and reserved, it indicates that he has not yet had the confidence to date alone, so he hopes to wear airbags to cushion each other; If he has an outgoing personality and is good at socializing, then this date is highly likely just a small social gathering arranged by him, or if he wants to help his friends introduce someone.
He instructed you to bring one of your female friends with you
Don't even think about it, they just use you as a springboard to get to know your sisters. Being an inappropriate matchmaker depends on your generosity.
Cafe, free park
Choosing a place for a date that is free or short of time indicates that the man is not optimistic about how much development he can have with you. He just comes out to try his luck, thinks about arranging other projects if he feels good, and leaves immediately if he feels bad about having a cup of coffee.
Restaurants, cinemas, art galleries
Choosing to date in this traditional setting indicates that he values this date very much and hopes to stay with you for a while and get to know each other better.
Nightclubs, KTVs
The first date is in these bustling places, purely treating you as a playmate, and it's almost enough for everyone to get high together.
