Source: Perfume: Perfume memories. The nose remembers. If you get a wiff of the perfume your mom used to where the connection is instantaneous.
My husbands parents took out infant son for a night so we could have some time to ourselves and rest. I got a little fixed up and put on the perfume I used to wear when we were dating. I hadn’t worn it in probably 3 years. When he came home from leaving the baby at his parents I gave him a hug and kiss. While we were hugging my husband started having a severe asthma attack. Allergies change. He’s allergic to that perform. So I have to shower while he uses inhalers and allergy medicine. Goodnight.
