I have a large dog who barks loudly and relentlessly when a stranger approaches my gate. She's an outside dog, so I have to go out to calm her down and let her know that this person is allowed to enter, so this is basically the greeting procedure- "Hi, you must be XXX, welcome. She sounds ferocious, but it's all a big show, she's actually quite sucky. Here, come on in, you must be exhausted".
I actually go pick the majority of my guests up at the bus stop, which is only a 7 minute drive, because my house is hard to find and most guests are arriving by plane and then bus.
