Do they always build the prettiest things on their sims? No - but they are often interesting and I like the creativity. Living a sim over from the LOVEHO resort became a running joke for us. But they were peaceful neighbors.
And I like meeting people by chance. I have mentioned before that the sim Jerremy and I live near the Route 7 waterway. That means boats come by and people wander through. They are usually just exploring. Also, our house is sort of big, so sometimes people don't realize it is a house. I never mind giving a tour (unless I am undressed) if asked. I would feel left out of things if we owned a private island. I don't know why, but I would.
