I love the smell of booklets and discs when you open a new package. Whether it be video games, dvds, blu-rays anything.
Anything that has a ting of a citrus scent to it does it for me.
I've always hated to smell of rain though especially on a hot day. I think it's most likely in combination with the asphalt but yuck so gross.'
Coffee and Cigs combined need to stay away from my nostrils.
