He's a non smoker and not an arsonist as far as I know
He does collect things though - he has an extensive coin collection for example
Anyway, he's decided he likes the look of vintage zippo lighters and has asked if he can have one and maybe start a collection. He also likes the look of the quirky new ones.
I've told him it's on the understanding that any he has- if I agree it - won't be being filled with fuel and he's fine with that
Still feels a bit weird to be letting him buy lighters though! Would you be comfortable with it in the circumstances?
