I agree with the general consensus - aloof, aware, but neutral.
Ryka is interested in people, but she doesn't necessarily care about them unless I'm greeting them or talking to them. She does have a bad habit of trying to sniff them if they get too close though, especially their hands after we do a walk-by greeting to strangers (smile, say "How are you?", then continue on your walk, lol).
She does, however, react to screaming, running, or suspicious characters. She's shown directed aggression towards people twice in her life so far: she charged and barked at individuals who came around the corner bushes while screaming, flailing their arms, and running at us unintentionally. It was two drunk teenagers chasing each other. She also lunged forwards and barked defensively another time when we were out for a walk near the park. Our neighbour from across the street saw us while she was out walking, then started towards us while raising her arms and yelling across the street at us asking a question regarding my SIL's dog. After I started talking to our neighbour and showed Ryka I was okay with her, she was happy to meet her and be pet.
If people are hooded, staring too intently, hunched, or following us too closely, Ryka will watch them very alertly. Ears up, posture forwards, following their movement. If they do nothing of consequence, she then just continues on like nothing happened. If I tell her to cut it out, she'll stop. But I like that she's alert like that, because I'm pretty oblivious. No one approaches me when I have her, and yet everyone approaches my SIL if we're out with just her Golden, haha.
