The Four Next Best Words!

The 4 next best words
The 4 best words ever, I always say to you!
And these words are very special to me!
You make me feel happen by the 3 words you use first
And I always reply with these 4 words!
You use these 4 words before you make the understanding
And sometimes by the first time you say the 3 words
I love you the best thing happens and
They answered by the next best words!
I love you too!
