I voted never
When the kids were younger, we used to eat together every night. We'd talk about our day, and just have fun talking.
But the mood changed over the years, and I started feeding the kids separately.. My DH was having a lot of emotional issues at the time and taking it out on my younger DD...
But now my older DD is in college, and the younger DD has a busy schedule. My DH works two jobs, and is rarely home at dinner time. So I eat with DD when I can... Some weekends we're all home bur DH eats in front of the TV in our room...
DD mentioned that she misses the family dinners.. I do too. I have the feeling though, that the memories of how it used to be will pale in the reality of what it is..
Growing up we always ate together. My dad would tell us ab out his day, He was a Cop and there were always interesting stories. It's a fond memory of mine..
Maybe a divorce will help! LOLOL..
