This is another thing I got a lot - with two white bulldogs, one significantly larger than the other - "are they mother and baby?" Um, they both have penises. And weird they always thought Linus was Bentley's mom.
You dont see me goin up to people askin so how much was your boob job lol
I do think it's rude, it's not anyone's business, especially a stranger's. I usaully just say something like... "oh it wasn't too bad". This question makes me nervous, I'm always thinking someone will try to kidnap them if they think they're worth a lot of $$.
