I think it is a little weird but hey its not something people talk about so maybe it is more normal than I think it is.
I associate people to smells. Is that weird? Each of my kids have a different smell. My grandfather will always be the smell of radio equipment and tools. My grandmother's perfume.
So sometimes I might have a trigger, like I will smell that scent or see a picture even, and I can almost smell that person.
But, it isn't just people. Summer has a smell, winter. Everything.
So there it is.
