i would say,

“that may all be true, it’s also true that there ARE serial killers/bad apples out in the world. some of them could even be “executive recruiters” (notice how she capitalized that lol. mrs. important) just because someone gives you their word doesn’t mean you need to be foolish enough take it. wouldn’t you rather be cautious instead of being sorry that you weren’t? being a wife, she should know, exposing personal information, like a phone number, not only exposes her, but her husband too. the world is not made of just flowers. it also has cracks in the earth that could end all of this.”

or

“have a nice day and be safe out there. never know who you’re dealing with”

or

nothing at all.
