I can taste the sweetness of the part

求翻译英文歌曲Sweetness的中文歌词，下面是英文歌词。不要在线直译，谢谢！！
She brings the sunshine to a rainy afternoon
She puts the sweetness in
stirs it with a spoon
She watches for my moods
never brings me down
She puts the sweetness in, all around
She knows just what to say
to make me feel so good inside
And when I'm all alone
I feel I don't want to hide, hide, hide
Today she brought me in
told me where she'd been
She put my mind at rest
put the sweetness in
I'll ask her for some time
to go and look around
She puts the sweetness in
with a sound
She knows just what to say
to make a sunny day
And when I'm all alone
I really don't feel that way
Tell me, how would you feel
with no world of your own
and nobody to hold
i just can't see the way
i'm so glad it's today
and you're here
you're here
She brings the sunshine to a rainy afternoon
She puts the sweetness in
stirs it with a spoon
She watches for my moods
never brings me down
She puts the sweetness in, all around
She knows just what to say
to make a sunny day
And when I'm all alone
I really don't feel that way
Oh how I need her so
I know she'll never go
Doo doo doo doot n doo
She'll never leave me, believe me, no
Doo doo doo doot n doo
She'll never go, no no no no no no no no no no no no

Happiness is a tree,
With joy,sweetness and excitement as its fruits.
Happiness is a house,
With gentleness,comfort and love as its furniture.
Happiness is a teacher,
Who teaches us to love,to sacrifire and own.
Happiness is a hope plus the faith of you and me.
Happiness is Spring's wind,
Summer's flowers,
Autumn's fruits
and Winter's snow.
Happiness is shapeless and invisible at all.
We need to touch it with full hearts.
Happiness is a perfume you cannot pour on others without getting a few drops on yourself
