After a brief fight between Stalker, Professor and Writer right in front of the entrance to The Room and after Writer's monologue about why he won't enter it, he nearly falls in there himself, but Stalker catches and pulls him to the ground, before beginning to cry. The Writer, while being used to have negative feelings towards Stalker during the whole journey, eventually shows sympathy to him by pulling him in a side hug, continuing to sit. The Professor joins them by sitting down next to them.
Near the end, Stalker's wife addresses the camera, explaining that, despite all the suffering she must endure as the wife of a Stalker, she is happy because she is with the man she loves, and would rather keep this life of passion and pain than live a "gray, dull life."
Bonus points if you kept everyone alive at the rookie village. You haven't forgotten how you started out, now have you? Barely anything to your name, saved by a more experienced Loner. Sounds familiar.
Generally, settlements and safe areas, due to the attitude of people in it. The loners are just getting together, sitting down, chatting, etc. Life in the Zone is tough and can be unfair, but despite this, they're still human.
In Call of Pripyat, a sidequest can wind up with you (wrongly) accusing Nimble of selling you a stolen weapon. You can ask Cardan about it, and the man speaks glowingly of Nimble, saying that he helped Cardan set up his shop, without charging him at all for the work or supplies.
