Why? Why, to give you a taste of your future, a preview of things to come. Con permiso, Capitan. The hall is rented, the orchestra engaged. It's now time to see if you can dance.
My people encountered them a century ago. They destroyed our cities, scattered my people throughout the galaxy. They're called the Borg. Protect yourself, Captain, or they'll destroy you.
The Borg is the ultimate user. They're unlike any threat your Federation has ever faced. They're not interested in political conquest, wealth or power as you know it. They're simply interested in your ship. Its technology. They've identified it as something they can consume.

You brought us here, you exposed us to it, and you cost us the lives of our ship-mates!
If you can't take a little bloody nose, maybe you ought to go back home and crawl under your bed. It's not safe out here! It's wondrous, with treasures to satiate desires both subtle and gross...but it's not for the timid.
Q set a series of events into motion, bringing contact with the Borg much sooner than it should have come. Now, perhaps when you're ready, it might be possible to establish a relationship with them. But for now, for right now, you're just raw material to them. Since they're aware of your existence...
Picard (realising the implications): ...they will be coming.
(telling Wesley about his early career) My mates and I were at the Bonestell Recreation Facility, which was something of a dead rough crossroads at the time, filled with an assorted bunch of galactic riffraff. When a trio of Nausicaans came in, they were clearly spoiling for a confrontation with a group of fresh-faced Starfleet officers such as ourselves. Well, everyone in the group had the good sense to give these Nausicaans a wide berth, to stand off. Everyone, that is, except me. I stood toe to toe with the worst of the three, and I told him what I thought of him, his pals, his planet, and I possibly made some passing reference to his questionable parentage. And the next thing I knew, all three of them were on me and I was fighting for my life. I was actually doing quite well for a while, too.
I had this one Nausicaan down in this somewhat devious joint-lock when, unbeknownst to me, one of his chums drew his weapon and impaled me through the back. Curious sensation, actually. Not much pain. Shock, certainly, at the sight of serrated metal sticking through my chest. A certain giddy warmth. In fact I do actually remember that I laughed out loud. Well, it pierced my heart, of course. Well, if we'd not been so near to a medical facility, I would surely have died.
Nothing. I was no hero, Wesley. I was an undisciplined, loud-mouthed, opinionated young man who was way out of his league. I learned a very hard, very painful lesson that day, but I learned it well. I hope you never have to learn it the same way.
