When I was in school, we ate as a family when schedule allowed. For most of primary school, sports were done in time for dinner. Music lessons were usually 1-2/week and often after dinner (instructor had a day job too). In high school, dinners as a while family were less frequent, but whoever was home would eat together. Same for the short time I lived at home after college - dinner was around 6pm and Mom expected me to let her know if I wouldn’t be home (default assumption was I’d eat with Mom & Dad since I was living there).
