RE: Stopping by without calling
If I'm busy or don't want to be disturbed I just blank the door and the phone unless I'm expecting somebody to call because of prior arrangement over the phone.
Why should we make up excuses why we're busy when people call? We don't need a reason to say why we don't want to be disturbed in our own homes; I'm not rude just assertive and politely tell them it's not convenient to call right now and if they push the issue and ask why I say that it's none of their business - it's as simple as that.
I had a couple of mates that didn't get the hint when it was time to leave and overstayed their welcome but they soon got blown out for good.If people just automatically assume that I have nothing better to do than act as host at the drop of the hat then it's their mistake. I hate ignorant, inconsiderate oafs.
It doesn't take two mins to phone me to ask if it's okay to call round first and my friends and family know that I value my privacy.
I have caller ID and an unlisted and number withheld private telephone number plus I'm on the free telephone preference service list

When calling some international and North American numbers they can have withheld number block and I just dial a number first to temporarily show my number and everything is clear to the recipient.
