Twitter because they just didn't get it. And this is someone who is on Facebook.
And as I like to over-analyze things, there are a couple of (what I would call safe) assumptions that I make about what someone is REALLY asking with this question?
The first is that part of the essence of their inquiry is "I'm already on a social network, why should I put time and energy into another one?" Another part of what's behind their query is "How is this different from what I'm already on?"
And, yes, there is an option to make your Facebook profile public and subscribe-able, and one can have a private Twitter account, so this obviously isn't speaking of individuals who would like to use each platform as such. But those users tend to be the exception and in terms of the general, intended use, I would say Facebook is more for building on and maintaining existing relationships while Twitter is more for cultivating conversations among friends and strangers alike, particularly when you take hashtags into account.
As I type this, I realize that one thing that clearly illustrates how the two platforms differ are by the tools they give you to interact with other people's content.
On Facebook you can Like, Comment, and Share. On Twitter, you can Favorite, Reply, and Retweet. And that's a blog post for another day, but if you have time and you aren't familiar with either set of interactions, definitely take a couple of minutes to just look it up.
And I digress. What's interesting is that even when I get through this, there are some people who've already made up their mind, and say they just don't have the time, which I call bollocks on if they're on Facebook. Or they say Twitter's just a waste of time, which might actually be true for them.
Whether personally or professionally, it isn't a platform to hop on just to do so. And it certainly isn't one to sign up for if all you're going to do is sync it to push from your other social media.
Let me know what you think about any of this. Are you a recent Twitter convert? Did you try it out and it just didn't jive with you? Are you the one your friends ask to explain it to them?
