It's been a quick 10 years since Friends aired its series finale, but the hilarious phrases, theme song, and hot hairstyles of the era are still fresh in mind like it never really ended. Also, it's probably because you love Friends and watch re-runs ever so often.

The ending of Friends didn't leave us without any important love lessons contained in those 10 seasons. Here's what the TV series has taught us about love:

1. Sometimes the best pickup lines just get straight to the point.


 

2. Even in a huge city like New York, you will inevitably run into your exes…and it will suck.


 

3. There's no harm in having a few casual flings. But you'll know when they've run their course.


 

4. Never ever date your roommate. It will be like living in the grocery store (and not in a good way).


 

5. When you love someone, you'll do whatever it takes to make them smile.


 

6. Your soul mate can also be referred to as "your lobster."


 

7. You should be very clear when you are and are not on break. It'll probably be brought up again.


 

8. You can only hide a new relationship from your best friends for so long—they will find out.


 

9. Stop stressing about rushing to the altar. You have plenty of time to meet The One.


 

10. And sometimes, the perfect person is even closer than you think.
