Sorry for your loss, William.
Yes, our footy family is large, and when we lose one is like a loss in the family.  Because what friends do you know that you laugh, cry, pull your hair out, scream, yell with, have a drink with to either celebrate or drown your sorrows.  You feel closer to your footy friends sometimes more than those in your other parts of your lives.  
I had a friend who bought a Ton Up membership year in and year out.  Trouble is, he wasn't a Richmond supporter, but he was such a friend to all of us at the club.  He passed away from a brain tumour a couple of years ago - and every time we play the Dees we think of him.  
I hope the club win for your friend today.
