I have the symptoms they describe - I really struggle to discriminate between different smells. I've always likened it to colourblindness.
Most plants smell kind of similar (whether that's leaves, grass or flowers, there's not much difference), and I honestly can't pick some (rather expensive and well regarded) perfumes from cleaning products and gardening chemicals. I would honestly prefer She wore some mild bug-killer than one of the perfumes she likes... it wouldn't smell quite as pungent.
So... knowing that... who wants to come for a bike ride in a remote state forest with me?
