Someone has parked on our drive for the third time this week - I have no idea who they are as both times they've been there when I come back from the morning school run and gone when I come back from the evening one.
The last owners of our house installed a small bollard that can be pulled up from the ground and padlocked in place. It makes it impossible to get into our out of the drive. I've already left 2 polite notes asking them not to park on our drive. AIBU if I lock the bollard and go out for a few hours?
