Where I am from in Europe people go out partying until 6am. There’s a saying amongst men that goes something like:

“Don’t say no at 1am, what you’d be looking for at 3am, and what you’d be paying for at 5am.”

With the current dating climate, there should be the following proverb:

“Don’t say no at 25, what you’ll look for at 30 and what you’ll be begging for at 35.”
