yeah, us Spurs fans ... doom & gloom is in our DNA. thats why our club crest is chicken-little standing on a ball when the sky is falling.We are uncomfortable with "happy". And not me. I tend to make things uncomfortable with my need to grind on others.
But in general, we get a bit happy and we find a way to disrupt that. We would rather chase a rumor that makes us mad/sad/etc. than listen to truth that is good.
I imagine a lot of clubs have supporters like this.
