Attending the Same Dinner Twice

A few years ago, my friend's family invited me to their dinner party. I do not know if she did not make the time clear or I did not hear right. I arrived one day earlier. They were confused about the dinner time and made dinner in an hurry anyway. Since they have also invited other friends on the next day, they asked me to show up again. So one invitation was good for two dinners. Of cause, I did not go empty handed each time. It is strange that the same thing happened twice with the same family after that. It is even stranger since I never arrive one day later. By the way, I am not a chihuo and not eagerly looking for dinner unless the invitation is from 涮婦. Now if they call me for dinner, I will confirm twice about the date.
