Who said anything about late night?
You did.
After work is not during the day or afternoon. It is usually not even still light outside after people get out of work.
Going out drinking alone with a woman while you're in a relationship is inappropriate no matter what time of day it is anyway.
@Mr.bocario She started off her comment as this:
Then she goes on what's appropriate behavior. This comment has nothing to do with a man & a woman having drinks "late at night" like she posts later on. Do yall think if people from the opposite sex consider each other friends that they want to spend everyday hanging out or late night texts or going on vacations without their S/O? If stuff like that is going on I agree that would be a problem
You were the one who brought up the drinking alone with another woman.
