when i came close to that bench, I saw these three "guys".
One second after I captured them, those two at the ground began fighting and ran away..
but I kept on watching the white one at the window.. and I remembered a lyric of a tango ..
the title is "Ciruja" ..a word of our slang, meaning "vagabond"..

Face to face showing big courage
the two brawlers crossed knives
in the dark, the Ciruja
faster with the knife
made the pimp pay too dearly his love.
Out of jail now and with no maiden,
staring at the sun on the sidewalk,
thinks awhile in the girl's love..
and sobs in his pain
