Yes, I'm always very well aware of my surroundings and notice lots of things. OH is the same. But we are different in what we notice.
He can remember faces and people and can often recognise someone from a fleeting glance several days ago, i.e. such as when we're on holiday by a hotel pool, he'll point someone out and say that they were in the check in queue at the airport, or they were at "X" attraction a few days ago etc. (Not just pretty girls either, so it's not that he's a pervert!)
I'm more aware of "things" and spatial awareness. I'm the one who looks for the quiet corner of the pool area, or a quiet area of the beach, or the restaurant etc., and hate sitting next to someone else when there's alternative places to go, or even waiting away from others at train stations or bus stops. I absolutely hate other people invading "my space" so I'm hyper-aware of not doing it to others. With "things", I can remember things like where cars are parked (not ours, but others), and I also have a good memory for things like car registration numbers, aircraft numbers, bus route numbers, etc. I noticed a suspicious strange old pick up truck on my walk home from work yesterday - I can still remember it's registration number now and where it was parked.
The difference is that OH would remember the driver's face and what he was wearing, I'd not have a clue, but I'd remember the reg number, model and colour, which he'd not have a clue.
Neither of us are ever in our own bubble, we're constantly noticing things, looking around us, etc., but for different reasons and what we remember are very different.
