It means never having to do anything alone.
Like going to the bathroom:
Taking a bath:
Or sleeping (comfortably):
It means no more playing chase without a shirt:
It means no messy floor in the kitchen when I'm cooking (other than if I spill some habanero salsa).
Unfortunately, the opposite holds true for a freshly mopped bathroom floor:
It also means no more solicitors come a knockin'. Or if they do, they sure don't stick around long.
And it also means no more pesky cats on my lap. That space is already taken.
