I used to hate it when slightly guilty pupils in my class would look at me with wide-open eyes and declare that 'they hadn't done anything wrong, miss'.. But I sincerely believe that I had done nothing whatsoever to antagonise or frustrate this lass. I was doing the speed limit the whole way. She was attached to my rear bumper the whole way. Even through two villages where there are speed cameras, I slowed to 30mph and she stuck there as if glued on. She was lucky, as my correct speed prevented her getting a fine through the post. Our narrow rural roads are all single-carriageway and mostly 60mph but sometimes the limit drops to 50 or even 40. At one point I wondered if she'd follow me right to our front door, and was glad that I knew my husband would be home. I will definitely turn off the main route next time and wait a bit before rejoining it! I have since wondered if she thought I was someone else - perhaps a lady who'd seduced her husband, or pranged her car in the past. If so, her husband must have weird tastes in stout elderly ladies!!
