Introucing my friends

Let me tell you about my friends Park and Jeon. We met when carrying out a big project 15 years ago. We always stuck together like ‘The three Musketeers’ at that time. We’ve meet a couple of times a month since then. We are of the same age and all have IT-relevant jobs and similar hobbies. Jeon and I are married but Park is single. Jeon and I want Park to be married but Park is likely to remain single.
When we go out, first we have dinner with a small amount of  wine and then we play billiards during a second round of drinking.
We love to drink and we used to go to 3 bars in one night, but as we've grown older we've started going back home earlier in the evening.
There is nothing we can do to turn back time.
