I vaguely remember saying to my mother that I didn't want to go to Sunday school any more. She said 'okay' and that was that, I was twelve I think, that was my last interaction with God botherers unless you count the six visits to a spooky priest to de-heathenise me and make me worthy of my bride to be (not the current lucky lady). :-)
I confess (see what I did there) to enjoying some of the hymns I've heard at funerals and weddings but don't sing along, maybe scared I get the bug again.
I remember attending a funeral and was beside my youngest sister-in-law who I've known since she was about 14, 35ish years ago now and was surprised that when the time came she crossed herself along with the other faithful. Never in all our acquaintance had I seen the slightest hint of religion until then.
Seems it gets into the blood.
Sorry, I've rambled.
