There's something about the smell of books. Not EVERY book, but some books, for sure. To know whether it's a good book, you have to open it up and sniff it. Matt still chuckles when he catches me nose deep in a book.
Some plastics smell really good too, though I can't tell you offhand which ones. Probably whichever ones give you cancer.
I've also always liked the smell of gasoline. Not, like, I would wear it or anything, and I'm pretty sure if I had to smell it all the time it would lose any appeal. But if I'm pumping gas and I get a good whiff, it's not all that bad.
Now, when it comes to more 'normal' things to smell, I have to say that my tastes have changed. I've never liked super duper strong perfume, (you know, the stuff that when you smell it you go PHHHEW) but too long and it gives me a headache. Since we switched over to using more natural soaps, stuff like Bath and Body Works is really hit or miss. It's too strong, too artificial.
Citrus fruits are a good smell - though to rank them, it'd probably be orange, lemon, then grapefruit. Also, I like my orange juice with as much pulp as I can get. If I'm not chewing half of my orange juice, it's a wasted experience.
I like a good vanilla. It's a good, safe smell. If it's too artificial, it can be a bit weird, but it rarely makes me cringe.
Spearmint is a smell that I like in soaps or gum, because it reminds me of my grandma. I don't know why, because it's not like she constantly had it on her. Maybe I was with her the first time I smelled it? I don't know.
Fruit smells in general are a winner for me, come to think of it. Maybe less so when it's grape or watermelon. I also never really understood the appeal of cucumber melon. That was a big one when I was in high school. But then again, I'm not really wild about cucumbers.
One of my favorites though, done right, is lavender. That seems to be a real love it or hate it kind of smell. REAL lavender though, like what I find in the garden, is amazing.
Cinnamon, baked goods, also real winners. I will not be upset if I walk into your house and smell either.
What are some scents that you really like? Anything weird?
