Tears

Roy Batty from Blade Runner in a first alien encounter, shows, in rhyme, the first and most important thing about the Earth to these visitors.

dear traveler from far away

I hope you have not come to stay

for while they might seem light and gay

any gift they give

you will repay

there is always a price, you see

borrowed, lended, but never free

the land, the air, the right to be

can be bought

for a fee

they may be mistaken for the rain

but these tears that fall are full of pain

you may receive but will never gain

only shattered dreams

will remain
