The leaves on trees

I think about it, if I could,
Step into your heart,
Without tracking in filth,
I think about it, if you would,
Use that beautiful stare,
To bring me back to elementary school,
I think about it, if I should,
And it makes me uneasy,
Because it would be the worst crime,
I think about it, and I fear that my love would,
Fade over time.
