Two scents really give me comfort and are as different as can be.
One of my grandmother's always used to wear Chloe perfume, and I can't find that scent now - or perhaps I have, but don't recognise it because perfume smells different on different people - but it always makes me think of her.
My other grandmother - she just always smelled clean and fresh, but not because of a strong detergent. Truly exemplifying the "so fresh and so clean" thing. I don't think she even wore perfume.
