Analysis of Tears of joy

I cried when you came here today. I guess you
are wondering why. Why I had tears in my eye.
I looked at you and saw many things I
Thought I would never see. I saw the sky turn
From dark to light, and the birds began to sing.
I saw the trees turn green and the sun rise to hot
I was able to lie in my favorite spot.
Without any worries of getting wet,
With the exception of the tears of joy I wept.
Your name is spring and will soon be summer,
these tears of joy I weep it's no wonder.
No lightning, no thunder, just you and me
Spring soon to be summer.
