Can't beat you for length of time supporting them Derek - well done on your dedication to the Spurs!
I recall during my junior school days going through a phase of supporting whichever team had the best looking players (it's a girl thing!) - flirting with the Hammers, Chelski, even Leeds (though never United or Ar5ena1!) before finally settling on Spurs around the age of 10, persuaded by my brother who at 2 years younger than me was a confirmed Spurs fan.
I grew up with a Gooner-supporting father (he'd supported them since he was quite young) which I think made me all the more determined to support another team. We ended up evenly split with my father and younger brother supporting the Goons and me and my other brother supporting Spurs (my mother keeping well out of it!).
I didn't get a chance to go to many matches until I was in my early 20s and then they always seemed to lose! The jinx was broken during the successful UEFA Cup run of 83-84 when I watched them beat Bayern Munich, then got tickets for the 2nd leg of the final at the Lane when we won. Joyous occasion.
Both my kids are Spurs supporters, having been brought up properly, though my daughter wavered somewhat when she was about 11 and supported the Goons for a couple of years before realising the error of her ways and returning to the fold.
Totally agree about the heartache supporting your team through thick and thin but that's what being a true supporter is all about isn't it. May the good times roll again very very soon.
