“Perfume is the key to our memories”
“Memories are the key not to the past, but to the future.”
“One of the keys to happiness is a bad memory.”
“History could hover, like a faint perfume or a memory stamped on the back of one's eyelids.”
“Sometimes he felt sure that the key to happiness was a poor memory.”
“Tis in my memory lock'd,And you yourself shall keep the key of it.”
