Another apology for the delay (I've been posting in 'Motoring')
As a child you probably regard whatever goes on in your house, or in your neighbourhood, as 'normal'. I just assumed that everyone had cereal for breakfast, some form of meat for dinner (usually based upon whatever was left over from the Sunday roast) and jam sandwiches and cakes for tea. I was amazed when I later found out that some people actually had anything savoury at tea time!
(Incidentally, I originally typed 'lunch' but I replaced it with 'dinner' because that's what I would have called it in my childhood).
I knew that many (possibly most) other families went away on holidays in the summer time (but, with the exception of one friend who once went to France, always within the UK). I dreaded going back to school after the summer holidays because we were usually asked to write about where we'd been and I always had to say that we'd only been on day trips (which usually actually meant a single visit to Felixstowe,12 miles away). Every year my father would spend hours studying brochures, working out where the best place to go on holiday would be. Every year he'd procrastinate over booking. Every year he'd wait until July and then spend a fruitless hour or two in the phone box across the road trying to find somewhere cheap that wasn't fully booked. The first time we actually got to go anywhere was when I was 15. (Real excitement! It was 'overseas'. i.e. the Isle of Wight!)
