Why does palm trees make me happy?

Is it because I'm Swedish, used to ugly pine trees (billions of them...), that I just love palm trees? Is it the long dark winters, dreaming of sunny days at the beach, that forever has planted a happy feeling in my mind when seeing a palm tree?

I'm sure the Swedish people in general would be more happy if their entrance to their local Konsum store looked like this. Having to go get milk and diapers sure is a nicer chore! (these are actually not really "natural", they were planted outside the store... want to buy a palmtree this size - no problems - have your $1000s in cash ready!)
