I definitely agree about the "having people stop by" thing. At the VERY least, call at least an hour before if you`re going to just come to the door, and a day ahead if you expect to be let in.
Houses are private. Ultra-super private. I can count the number of times someone who doesn`t live here has come into my house on my fingers.

People tend to judge people on their homes, and expect to be judged on theirs. So it is very important to be ready for someone to visit. Someone suddenly stopping by and coming in is pretty awful as it gives you no chance to get ready. As most people do not keep their homes in an always-ready state, it is extremely rude to just show up out of the blue.

So... Meeting outside is much much easier. If someone does just show up at my door, they don`t expect to be let in, so I end up going out and talking to them outside the front door. It`s just how things are. Home is a private nest.
