Kelly, why would he leave his car by the mail boxes if he were house sitting?
True. In fact, if someone hired a house sitter, they'd want a car parked in the driveway to reinforce the fact that someone was there.
I've never understood why he left the car there. Double driveways & street parking. It's almost like he was saying "I don't want to be a bother."
...or "I'm going to be gone awhile, so I can't block anyone's driveway."
I don't think street parking is really allowed; it's even mentioned in some real estate ads that there's no street parking.
That particular parking place is the *only* one like it, in all of SCA. It's in the only cul de sac that's not completely surrounded by homes, so he wasn't in front of anyone's home, nor blocking their driveway.
If he found that spot at random, he was lucky. He'd have had to search all through SCA to find such a spot in a noncommercial area. It makes sense that someone told him where to park...and of course, he could have been there previously.
