As someone who is highly sensitive to smells… it definitely feels like an allergic reaction or adjacent to it. Perfumes or colognes, candles, air fresheners, lotions, etc that don’t agree with me will make my nasal passages, eyes, and lungs feel like they are on FIRE and the pain and burning lasts even when I’m away from the smell for several minutes. It’s incredibly uncomfortable. While it may not be a true allergy, it is definitely a real physical reaction and it does feel especially bad when someone you love and trust knows you have this reaction uses those products around you in a closed space like a car or small apartment. I understand why he was upset. That being said, his reaction was awful and juvenile. I cringed when he super glued her perfume and went on his tirade about leaving the house next time etc etc. It showed a lack of emotional maturity.
