Why people don't have gills?

We are tired, we haven't slept for days, we drink too much, the stomache aches, our eyes are dry, and we are running out of money, there're not more photos, and we use old ones, we don't read new books, we just get tired of reading someone else's stories, we stopped buying clothes, we use promo ones, we look like homeless but we feel at home. 

Estamos cansados, no hemos dormido en días, bebemos demasiado, nos duele el estomago, nuestro ojos estan secos, y ya no nos queda dinero, no tenemos mas fotos, y usamos las antiguas, no leemos libros, simplemente estamos cansados de leer las historias de otros, dejamos de comprar ropa, usamos la de propaganda, parecemos indigentes, pero nos sentimos como en casa.
