have you tried it before? or this is your first encounter the encounter to a thought a thought of a parallel universe where you read a book backwards sing backwards and do backwards it might seem alien at first then it might not interest you but you have definitely been there.
Every time you think of her your life runs backwards first from the end the last time you saw her the last fight the last kiss the last smile then comes nostalgia nostalgia of all the good times all the days under the sun all the moonlit nights till you reach the beginning that is, the very first time the falling at first sight the rhythm divine the first kiss the texting at night.
Till the potion potion to the parallel universe wears off and leaves you with a smile.
