Then and Now

Where did the time go?
You were just a puppy.
Now you are full-grown.

Where did the time go?
You were once small.
And now you stand tall.

Where did the time go?
Then you were so fragile.
Now you are so strong.

Where did the time go?
The puppy I had at the start,
Will always be a puppy in my heart
Even though you are an adult.
