“I’ve been absent from you too long. I miss you so badly and yet this being apart makes me realise you’re not simply the faithful man who loves me so astonishingly well, but an angel, sent for some unfathomable reason to look out for me. I should have realised this truth years ago because you are so extraordinary, so unlike other men, so unlike me, this weak, vain, faithless creature you have been so intent on saving from himself. I should have realised from the first moment I saw you in that trench, when I fell so badly in love with you and hoped you wouldn’t notice. Or perhaps not then, but later, when you saved my life so often just by lending me courage when I was half-mad from fear. How much courage you had to spare – I will never forget. But angels are courageous, aren’t they? I should know. I have never understood why I deserved such grace.I don’t have your faith, Patrick, or your love of God. I am uncertain and afraid, I wish you were with me now, not just in spirit, as I know you are and always have been, but here in body. I need to cower behind you, because if God is real He might be kinder knowing you loved me.If angels need to pray, pray for me.”
