Soud Proust and his biscuits. I've literally just had the smell of my parent's livingroom carpet tiles waft in to my nostrils. A complete hallucination, of course, but triggered by seeing the lego I grew up with. None of that Bionicles shit... proper lego that just couldn't wait to embed itself in your parent's bare feet.
These are just burnt into my memory. I can look at them and say 'oh, that was the one you could get for free with weetabix... and that one was the first to have the bendy pipes...'
I feel a trip to Kingston coming on...
