Worst Day

In Calvin Harris's words:

My first mistake was letting you into my life
My second mistake was allowing you into my bed
My third mistake was loving you more than I should
Oh, I really should know better
My fourth mistake was sitting with you,
While you're telling me that you can't do this anymore

This must be the worst day of my life
And it's true 'cos all I wanna do is be by your side

I'm walking home and listening to MP3s
Just how did I let you decide to destroy me
I'm missing you, it crossed my mind that our heart will bleed
The love that I have left behind is gonna finish me
It's one of those days
