Now that is a serious amount of time in which we have been forced to be underachievers.
However, in 1983 I convinced my parents to take me to the F.A. Cup Final because "it may never again happen in my lifetime" (I was 12 at the time and was a realist even then). Looking at life more optimistically these days a new ground and improved fanbase may in time lead to an upturn that could yet prove my 12-year-old self wrong and if that happens, then 13 years of woe (10 if you discount our promotion/champs years) won't seem like such a loss.
