the boy vs. girl issue

so I never really realised wot the fuss was about when people got baby genders confused.. An old lady comes up to a young mum at the supermarket, looks at her baby in the trolly, and says "my, what a lovely little boy you have". After a pointed glare, the young mum dons a superficial smile and says "why thank you, but she's actually a girl"
Honest mistake?
perhaps..

I was out taking the puppy for a walk this evening, when an old lady (!) starts "oohing and aahing" at the little guy.
So I said "Hey Ceaser, say hi"
At which point, the lady looks up at me, beams and says... "awww... she's adorable"
Now honestly.. WHY (oh why?) would anyone name a female dog CAESER!
Its not a girlie name..
and much of the roman empire would be very distressed if the average American today thought that it was.

Young mums around the world.. I feel your pain.
