We Must Stop Meeting Like This, I

 is an unmarked quest in Fallout: New Vegas.

Quick walkthrough
In Goodsprings, thank Victor for rescuing you and try to find out if and why he's tailing you.

Detailed walkthrough
As you meander around the settlement of Goodsprings, and you haven't met Mr. House at the Lucky 38 Casino, you may spot a Securitron zipping around on its single tire. Why, it's Victor, the good-time cowpoke Securitron! If you spot him in Goodsprings, you can thank him for rescuing you from a shallow grave, ask what he's doing, ask about the men who jumped you, or tell him to stay out of your way.

Victor shows up in Novac, as well - to the right of the entryway, during the main questline when you pass the town. You may also run into him waiting by a building with tracks next to it when going the long route to the Strip (nearest to Boulder City).
