"If one day I see you inadvertently, please pretend you do not see me, because that, I will not have to hurt again."
This reminds me of the Bob Dylan song called "I Don't Believe You (She Acts Like We Never Have Met). Here's the last verse:
I'm leaving today,
I'll be on my way
Of this I can't say very much.
But if you want me to,
I can be just like you
And pretend that we never have touched.
And if anybody asks me, "Is it easy to forget?"
I'll say, "It's easily done,
You just pick anyone,
And pretend that you never have met!"
