i could say

Since you've gone I've lost a chip on my shoulder,
Since you've gone I feel like I've gotten older,
And now you've gone it feels as if the whole wide world is my stage
And now you've gone it's like I've been let out of my cage,

(...)
And everything was always about being cool,
And now I've come to realise there's nothing cool about you at all,


Lilly Allen, I could say
