How boring is it to be a sheep and tell others "I support Chelsea!" or "I support Man. Utd!"?

As a United fan I do resent the fact that there are so many and in truth i wish I chose a different team 12 years ago (19 now) but when you've supported a team for that long its not as if you can go and 'change' your club because people think its too common. Too much emotional investment and not to mention money! Family have nothing to do with Manchester or the area. I simply started supporting them because years ago on 'BFBS' ( British channel for army families overseas) whilst living in Germany the only team that ever seemed to be shown was United. Not to mention my local sunday club was packd with United fans. Frankly i don't need a reason - RED DEVIL 4 LIFE!!
