I have a few melancholy scents myself, but boy are they defferent from yours. Top of the charts is En Passant. That's right, En Passant. Something in its delicate wet lilac accord strikes me as intensely nostalgic, and leaves me slightly misty-eyed whenever I smell it. In second place is L'Eau de Ryokuei - another light, fresh green floral. What gives? I don't know but the Menard scent delivers a similar, if milder dose of nostalgia to my olfactory center.
