You

I can't live without you.

If I didn't have you how could I spell yoga, oranges, or ultimate frisbee.

If you did not exist how could we say yesterday, old, or upset. 

I don't see how I could live without you. 

If you wasn't in my vocabulary I couldn't say yes, out, or utopia dammit. 

If you weren't here yellow wouldn't be a color, odor wouldn't be used to describe, and a uterus wouldn't carry a baby. 

I just find it hard to see my life without you.

If I can't have you I wouldn't be able to smile, laugh, and enjoy my day.

Because if you weren't you, I wouldn't know what to say.
