"I didn't want to run into." Sven waved casually toward the group of people that were steadily distancing themselves as the other stood still. "Your group of friends take up a lot of space...and don't seem to realized you're not with them anymore."
Of course, the assumption was that the group he'd been with hadn't know him at all. So much the better. "I was wondering if you could recommend a place to grab a bite to eat." Not a complete lie, since perhaps this person's tastes differed from Sven's own. A shame that Sven wasn't all that hungry. He glanced to the side and got out of the way on the sidewalk, leaning against the side of a building. Test number one of someone being interested: they followed.
Not that Sven's pheromones weren't already a long leash. Purely by accident, pesky power.
