we are quite limited in what food we have in the house cos i don't like to have a lot of junk about.
i only drink water, milk and decaffeinated (sp?) tea and my mum has the decaff coffee. because of this we don't buy squash, fizzy drinks, juice etc. we also don't generally have biscuits, crisps, chocolate, cakes.
if you don't actually eat something but it is often something you might offer someone when they pop round do you buy them or not bother and go for the if they don't like it they can lump it school of thought?
