Swede here. Growing up it was not uncommon not to be invited for dinner, but more often than not I was, otherwise l'd just stay in my friends room and play while he was eating real quick. I think it's been said before but most of the time everyone went home at the same time to eat with their own family.
I also remember my mom being upset when I ate at friends houses just to come home and not want the dinner she had been cooking because I was already ful. So I'd usually decline a dinner offer at my friends house because I knew my mom had dinner ready at home. And I think my mom knew that my friends parents had dinner ready for them when they eventually went home as well.
