Why Didn't I know?

I thought of you as a friend
And Nothing more
But I have feelings
That I never thought
I would feel for you

We hung out, great
We had fun, even better
We laughed, enjoyable
But that wasn't much
You're just a friend

But I can't say that anymore
I have feelings for you
That I never had before
The funny feeling

Of Disbelief
Fills my gut
Do I love you or not?
Sure we could just be friends
But I guess I like you more than that
Why didn't I know this before?
