Along side the I was there moments are the I should have seen it but didn't moments. It doesn't have to have been at the ground. If you were watching on TV and decided to go to bed or watch something else or go out or missed an historic moment for any avoidable reason.
Mine dates back to 1977 and Geoff Boycott's 100th Hundred. I was at my aunts house and in those days most people only had one TV in the house. I'd been watching all day when my aunt came into the room and turned over at 5:45pm for the ITN News. It was only a 15 minute window and often Boycs took a long time to get through the 90's. On this occasion however Greg Chappel was inexplicably bowling and gave him a nice leg stump half volley - and I bloody missed it.
