MY favorite smells are pine tree (especially in combination with salty sea) that brings back good childhood memories. It almost makes me cry thinking of it. heh.
Also: Coffee Is The Best Thing Ever.
Saffron is a good smell as well. Spearmint, liqourice and chocolate too.
So many smells I've probably forgot until I smell them again.
Oh and also another smell
but I don't think it's appropriate to mention it here.
