Now it seems the boyfriend that has picked up the same habit and often stays out to between 3-5am
She explained that she and her partner have been living together for two years
It can be difficult living with your partner when you've got different schedules and social lives.
If one of you stays out really late, it can keep the other person up - which isn't fun at all. It's especially annoying when one person complains about it, and then does it themselves.
Which is why one woman has revealed she charges her boyfriend £40 (approximately Sh5200) if he doesn't make it home after a night out by 4 am.
Writing on Reddit, she explained that she and her partner have been living together for two years.
Despite being a "natural homebody", she'd developed a drinking problem when they first started dating, due to the death of her mother.
She wrote: "After moving in together, I was still wrestling with alcoholism and stayed out a handful of times (about five times in a year) until 3 am.
"Frequently, I'd irresponsibly allow my phone to die while I continued drinking. Every time, my boyfriend expressed that he hated this."
Now it seems the boyfriend that has picked up the same habit and often stays out to between 3-5am, giving her little information about his whereabouts.
She said it's not so much the problem of him going out as it was the fact that he would get angry when she stayed out late - and she stopped doing it for his benefit.
Her solution? A curfew and a fine if either person breaks it.
"If either one us aren't home 4 am, we have to give the other $50 (£38) and no one can be angry," she explained.
"My reasoning is that he's either going to tire of paying the $50 and come home on time or afford me the same level of understanding for occasionally staying out until the bars close."
The Reddit user asked people whether she was being unreasonable and most replied saying that it's not a good way to deal with relationship problems - and indicates wider issues.
"Your lifestyles are not meshing," replied one person.
"This $50 thing is a bad idea, it sounds like it's going to breed resentment, not actually encourage him to get home on time.
"You don't seem to be able to properly communicate your feelings to each other, or he just doesn't care how you feel," another commented.
