When they have to "line up" a baby sitter, it probably means a soft no? It's not like they have to start interviewing and doing background checks to find a babysitter to go out swinging or on a date or just to get out of the house. They got one somewhere.
We always had a couple of babysitters available. What else are kids good for?
Ours are grown and gone now. We may be the babysitters before too long
It seems lots of people want to swing until called on it and then they come up with lots of excuses not to.
