Immediate family? 5 years and counting. Moved across the world and haven’t been back since. I’m planning to visit for vacation in the next year or so though.
I guess for me would be 3-4 months in covid lockdown, 2020. I live by myself in proximity to family, but some of that family were vulnerable so I wasn't taking any chances. Not a nice time.
Back before I started working for myself, I often couldn't get my job to approve time off, so I would go a whole week during the holidays when my wife and kids went to visit their grandmother. That's not really a problem for me anymore though, since I write my own schedule.
