Family members dropping by isn't an issue for me, only 2 sisters, we're not especially close and they both live a couple hours away. See them maybe 2-3 times a year. Don't really like people dropping by unannounced, but that seems to be the custom around here and I've gotten used to it.
I don't discuss politics with anyone. I really don't care who you voted for, life's too short to choose your friends based on which crooked politician's name you checked on election day, religion (or lack thereof), or anything else that's superficial. I only ask the same.
While I can be a bit of a hermit, likewise I wouldn't like living without friends around. Love my wife dearly, but it's not fair for either of us to be totally dependent on one another for companionship.
