I don’t want to belittle what must be a really unpleasant thing to suffer from, but I keep thinking of Mary, my favourite character in Ghosts. Smell is the most powerful sense when regarding memory, isn’t it?I know that sometimes, if I smell something unpleasant, the smell seems to remain in my nose for a long time afterwards. It’s quite a complicated sense I think.Sometimes, when I think of peoples homes I can imagine the smell of that house eg my daughters house makes me think of the smell of the washing up liquid that she uses and my cousins house conjures up the smell of Lynx that his son used to wear.
