On/Off

I wish it could last
But the moment slips into the past
I blink and it moves beyond my grasp
And then it's gone

What does she expect?
There's no way I can be perfect
Now I'm trying to forget
That she is gone

I wish it could last
But the moment slips into the past
I blink and it moves beyond my grasp
And then it's gone

I can't see in black and white
Instead it's different shades of grey
It's hard to let go of yesterday
When you're hanging on
