We havent had a postman on our street all week. I've asked two of my neighbours and they haven't had any post or seen a postman either. Is there any reason that he might not show up all week?
You could hope that "No news is good news", but it might be a good idea to check with your local post office to see if there is a problem. It could be just a case (although very unlikely) that you don't have any mail.
