"Part owning?"
Is that like a time share?
If a client asks me directly about my children (it's obvious that I have given birth) I may say something like, "Oh, let's not get personal." The most intrusive guy, who really got on my nerves, I just said, "Oooh... I'm not sure it's appropriate to discuss children in a sexual context" with my eyebrows arched. Made him feel like a pedo for even asking. Cunt.
