My approach to any new visitors is the same, whether it be in my living room, my yard, my town, my state or my country. I think Jimmy Buffett described it best

So I approached him, I said "Mr. Bear, I love
Every hair on your twenty-seven acre body
I know you got a lot of friends over there
On the other side of the hill

There's ole' rare bear, tall bear, Freddy bear, Kelly bear
Really bear, smelly the bear, smokey the bear,
Pokey the bear

I want you to go back over there tonight
And tell them I'm feelin' right
You tell them I love each and everyone of them
Like a brother and a sister

But if they give me any trouble tonight
I'm gonna run every God damn one of them off the hill"
