If you don't already know a close crew of friends, I would suggest starting an Empty Nesters In Training group.

Get together once or twice a month or so, makes the transition easier for when your kid graduates HS for college.

And also good luck with the job!

I have a great job but we might go public in 2025. So cue the layoffs.

Most layoffs when companies go public are usually to support staff. They don't want to do anything that can affect revenue for the first few years.
