I suppose I'm one of the lucky ones that has a partner that shares the hobby.
I also help with my wife's hobby of collecting vintage model lorries and busses.
And we both enjoy our vintage model railway collection.
I suppose we are both addicted to modelling, as my wife also designs and builds 1/12th scale dolls houses, I usually get involved in the cutting out and the hidden wiring.
It's just the way we are, our grandchildren love what we do and especially the 5 year old boy as he likes to be involved. It's a pity we live 30 miles apart.
