Kilogram

It started physical But there's no shame there
 I was what you needed and I was happy to stay there
 you said I was your constant, your ideal
 And I started to think that the thing we had was real
 The days turned to years right in front of our eyes
 You kept me locked up here, I felt like a prize
 you said I was the best you'd had and I clung to your word
 I wanted to be what you needed, and for you I was standard.
 I was lost for so long but you showed me who I am
 I would never be wrong if I was your kilogram
 But now it's all over - If your calculations are correct
 I'm more than a number - And that is why we're wrecked
 I know it makes sense
 I know you have needs
 But what do I do now
 What about me
 Could you really replace me with nothing but numbers?
 I suppose that you can
 But who will I be if I'm not your Kilogram
 I'm searching for meaning
 in your eyes but they're blank
 there is someone else, I know it.
 somebody named Planck
 I know it makes sense
 It's logic, it's smart
 but I did nothing wrong
 do you not have a heart
 would you let a committee of strangers tell you who I am?
 and will you really be you, without your kilogram?
