How many of us have had to deal with a version of that retort?! It's hurtful and I suspect - for some - that's partly because of the nagging feeling that our families may have a point.
But do they?
I was 15 when I got baptised, is it reasonable that as the 50 year old man I'll be on my next birthday I continue to be held to a decision I made as a schoolboy?
If the agreement I 'willingly' entered into as a child is changed by the other party without any debate or consultation with me why should I feel obliged to honour it?
Screw 'em!
