Sam Smith - Too Good At Goodbyes

You must think that I'm stupid
You must think that I'm a fool
You must think that I'm new to this
But I have seen this all before

I'm never gonna let you close to me
Even though you mean the most to me
'Cause every time I open up, it hurts
So I'm never gonna get too close to you
Even when I mean the most to you
In case you go and leave me in the dirt
