Summer:Fan base whose team won the Cup talks about how amazing the Cup run was. Fan base of every other team talks about how "next year is our year"
Pre-season:Find out which team is playing yours on opening night. Start trash talking them immediately. Continue throughout the pre-season.
First few weeks:Talk about how exciting all of those past year playoff rematches are going to be.
Next few weeks:Realize that they weren't that exciting at all.
Middle of the season:Settle into a comfortable pattern of either joy or misery. Depending on which one you're going through, say either "This is totally going to continue into the playoffs" or "The playoffs are months away, not worried"
All-Star Game:HOLD HANDS AND LOVE EVERYONE
End of the regular season:Start crunching numbers like you're a statistician, to figure out the seeding and how many games your team can lose and still make the playoffs.
If your team makes the playoffs:"We're making a deep run, this is our year"
If your team doesn't make the playoffs:Cry softly then decide which team you hate less to win.
Repeat every year until you die of a hockey induced heart attack.
