Is it normal to not answer the door if you aren't expecting anyone?
Obviously if I've invited someone over or I'm expecting a package then of course I answer.
But I'm talking about neighbours dropping by unannounced, door to door sales/religious people, or just random stuff. I live in a pretty friendly area so it's not like I'm scared, just sometimes I'm busy doing stuff or I can't be bothered talking to someone. I like my alone time, I don't get much of it and it's kind of sacred to me. I hate the mental interruption of an unplanned visitor or problem, conversation etc. when I'm working on a project in my shed or just trying to read a book or something.
But sometimes I get worried because if someone can tell I'm home (like they see my car or lights on or hear music) then what would they think of me not answering.
Is this normal? Am I rude?
