Do you feel happier when you see a tree?

Yes I do, it reminds me of my childhood when I would climb them and relax underneath them in the shade they provided.
I would much rather have trees around than electrical/telephone polls.... Which are kind of like zombie versions of trees in my opinion hehe

As i get older yes cherry blossom in spring is a beautiful site,

I love trees. When I was looking for a house, I chose an older house over a brand new one because there were no trees in the new neighborhood, and my current one has trees everywhere.

Why of course because tree is good, smells fresh and I heard if you stare at it helps your eyesight. My sister love plants, her nature :D

Well, I do and I have a number in my garden - however, I am not sure that my neighbours necessarily agree - my ornamental maple has just finished dropping loads of leaves all over them.

I would feel slightly more cheerful, yes,unless it was a Leylandii, but I think I would feel a whole lot happier if I saw a moving forest of trees as in Macbeth .
