I partied until 4 a.m. when I was in college. My Gen Z twins are home before midnight and work at 6:30 a.m.

The author of this piece reflects on how his 20-year-old twins, Charlie and Thomas, have a very different lifestyle compared to his own experiences in his 20s. At 4 a.m. on Saturdays, his own party nights often ended with a kebab. In contrast, his sons start their weekends at 6:30 a.m., working in the produce department at the grocery store they've worked at since they were 16.

On weekdays, they fit their shifts around their university schedules, which they both excel in. Neither of the twins is particularly social, with neither having a girlfriend, but they both do enjoy gym, golf, and hanging out with friends. They rarely drink, and when they do, it's usually with a girlfriend or at an occasional rave or concert.

The author's parents never saw him on a weekend when he was young, but he knows that's much different from how he now sees his own sons. His wife, Cece, is American and attended LSU, so she is used to the party scene at her university. She's surprised by how little his sons go out. Some friends of the author's have kids that drink too much, stay out late, and sleep all Sunday, but the author feels he has nothing to complain about compared to them.

Even his sons' birthdays don't seem to be special occasions for them. At their 20th birthday dinner, neither of them would have a beer with their family or go to a bar. The author is proud of his sons and believes they have a very different lifestyle to what he had in his 20s. He is not worried about them, as they have jobs, good friends, and good grades, and he would like them to occasionally come home late with a story they can tell their grandkids instead of being passed out on anyone's front lawn.
