When we beat England after a close match..I become fan again!   . I used to be a bit Rugby fan...not anymore...though I still follow the 6 nations and the world cup.

My best sport live experience was that France/New Zeeland semi final in Twickenham when we came back in the 2nd half to beat the kiwis with all the stadium filled with brits cheering for the French team! Loved it.....except that I got a seat there thanks to a kiwi friend of mine so was surrounded by angry kiwis.

We always produce our best game versus the best teams and then see us lose to a boring team.
