Celebrate the hell out of it, life is too short, use it as a celebration of our new regime and coming out of the dark hole we were in.
I remember going to watch Aberdeen, the fans had been spoiled with League Championships, A Cup Winners Cup and a smattering of Scottish Cups. I watched a particular performance vs raith where Aberdeen were full of movement and invention, they took Raith apart but only capitalised on 3 of the great chances they had carved out. I stood up, expecting an ovation to the players for a great game and was pushed past by about 3,000 people mumbling about, "only 3-0" and "second in the league is no use". Fast forward several years and Aberdeen are lucky if they can beat Partick at home and finish in a consistant mid table slot. I bet those grumbling supporters had wished they'd enjoyed 3-0 wins and 2nd place a bit more now.
Sieze the moment and celebrate like it's the last cup we will ever win, for all we know it might just be...
