Do you have a very good sense of smell?

I have a friend with an exceptional sense of smell, and at first, I thought he was bluffing.

One time, when we were out to eat with a group of 20 and when we were about to leave, (only five of us remained since the others had left earlier) we realized someone had forgotten their sweatshirt, and my friend sniffed it, confidently stating who it belonged to. To our surprise, he was right. I thought maybe he had just remembered whose it was.

However, similar things happen often (not only sweatshirt), and heโ€™s never wrong but I was still doubtful, I was finally convinced when he told me he could sense my best friend approaching. I had arrived early to class, and he did too; he was busy drawing when suddenly, he sat up and said he could sense her coming and that she would be there soon. Sure enough, two minutes later, she arrived.
