Un poema en inglés con el present perfect y el past participle?

Sitting in the parkin the cityTall green trees all around meSunlight filtering through every branchThus I will do my best to be quite wittyThe silencein the parkcalms my spiritPeople walkingslowly so peacefullyManyof them sitting downreading a bookSomecome and go riding a bicycle so happilyNot far from meThe sound of water in the brookAchild playing witha swingAnothersitting down playing in the sandWho knows what tomorrow will bring, although we live far away in another landPeople arebornPeople dieAll of usstrive to be happyOthers think life can be rather crappyIn the end, one daywe all will flySitting in the park, onan autumn pleasant dayWatching peoplewalking bySo many thingswe want to sayHowmany timeswe willhave to cry.
