One of my first poems

I thought

I thought, 

I knew she was mine.

Then I saw her in his arms

and realized she was never mine

at all.

The objects of this poem were Marilyn Timothy and Danny Jonas.  I dated Marilyn my senior year, but I think the relation was more one sided as evidenced by my seeing her with Danny.

I found the original version:

I Thought--

I Knew--

You were mine

I saw you in his arms

My heart turned cold

You were never mine at all.
