pianistclare, I think MT was referring to the time when his/her children were younger, something like less than 10 years old. I cherish the time with my two young daughters (7 & 8) and I know exactly what MT is talking about. After I get home from work and before dinner, we will just sit together doing whatever. One of us might be watching a show, another playing on her ipad, and another coloring; nonetheless, we all stay together in the same room and just hang out.
At the time, it seems like a waste of time because the yard isn’t getting cut, the dishes aren’t getting cleaned, the clothes aren’t getting washed, emails aren’t being answered, just spending time with kids doing mindless things … not to be regrettable as kids grow up to adults, they usually don’t want to waste time with you either because now they have their own lawns to cut, dishes to wash, clothes to launder and life to live.
