There's simply no way you can tell a woman you work with that you disapprove of her relationship with her adult child, no matter how much you think it would be better for him to move out.

If your wife briefly corrects someone with "Actually, I'm bisexual" during conversation, it hardly sounds like attempting to remain an object of desire to me.
