I am not sure if I am BU or not. DH and I have had several discussions about it, and he is def more live and let live about everything than I am, so would value your opinions.
We live in a street with unrestricted parking, but near a busy shopping area. (small town)
There are quite a few driveways, but they are not very big, as the houses are not set far back IYSWIM.
I often come home (in the car) to find that someone has parked over our drive, and therefore I have to park down the road or round the corner, lugging DS/shopping/pushchair for quite a long way. Occasionally it is a neighbours car, but mostly randoms.
I do realise lots of people dont have the luxry of a driveway at all, so that is why I want to know if I should just let it go, and find something more important to worry about. 
It just irritates me sometimes, as I was always taught that you NEVER parked over a driveway, out of courtesy, both my my parents and my driving instructor.
Will stop wittering, just honestly wondered what other people do/were told?
(Thanks if you read it all!)
