Heightened sense of smell is the bane of my existence. Some colognes and perfumes give me an instant headache. Those so-called air fresheners are just fuckin killer for me - they are not fresh at all. My wife refrains from wearing perfumes and I love her for that.
Same for me. If someone walks in slathered in artificial smells I have to leave the room. I would genuinely prefer my beloved to stink of manure if they had to stink of anything.
I asked two of my colleagues at work (on separate occasions) if they would refrain from wearing the cologne they were using - I even offered to purchase it from them so they weren't out any money. One of them stopped wearing it (and didn't want my money) and the other one said "Would you rather I came to work smelling like BO?!" Yes... yes I would.
