A Three Word Emotion

A four letter word
Combined with I and You
Just to tell someone
That powerful word
To someone else
And to them, it could only mean so much
Like a child and a mother.

Love combined with I and You
Is not just to tell someone
But would also describe something else
An emotion that would fall between happy and calm
But you would never know which
Until you take the time.

Love brings joy to everyone that thinks about it
But would then, just then
Would the not have any worries
Because they thought about love
That three word emotion
As to what I refer to it as
That emotion you share and say,
I love you
