>>20274706At the end of the day Rocker, you're the only one who can answer that question. That is definitely more time per week than I spend but I also don't live close enough to my parents that I can just drop in for 4hrs every weekend.
That said. If it feels kinda aimless for all involved you could consider dropping by for a specifc meal like a few other anons have suggested, or some other non-passive activity you do together. That way you get some time to talk with them and the actual amount of time you interact is longer even if time spent is shorter.
