If you needed anything, you could go to him. ‘Bren did a physical education degree at Uni and went to America to play rugby. He was really into sports and very fit. ‘There are usually eight or nine people who work in the office; it’s not very big.’ Brendan died in hospital despite the best efforts of staff One of Brendan’s former rugby clubs paid tribute to him and wrote: ‘Yesterday, Old Colfeians lost a member of our family, one of the kindest, funniest, most genuine people you could ever meet,’ the post said alongside a reel of photos of Brendan on and off the pitch. ‘Brendan lit up every room he walked into, forever smiling, always cracking a joke and always full of life. ‘His absence will be deeply felt for a long time to come. We will miss him more than words can say and we’ll always carry his memory with us. ‘We are also mourning the loss of his beloved father, Terry, a long time supporter and sponsor of the club. ‘Our thoughts and prayers are with their family and friends during this incredibly difficult time. Rest in peace, Brendan McMillan.
