The purpose of an 'At Home' or whatever you want to call it, is to socialise with ones friends and colleagues etc:
And in this case, to ogle a woman while your wife is at home with a sick child.
It's another proof point that these social conventions and protocols both promoted and mocked in these 500+ posts don't actually improve civility, all they do provide a facade for the lack of civility to hide behind.
At least the cave men were honest about what they were after.
Cynically yours,
