My friend

Empty your mind. Be formless, shapeless. Like the 'sustitut@'.
You put the 'sustitut@' into a man and s/he becomes a man.
You put the 'sustitut@' into a woman and s/he becomes a woman.
The 'sustitut@' can arrive at A Guarda and the 'sustitut@' can arrive at Ribadeo.
Be sustitut@, my friend!
