Input: Text: as i was walking to school yesterday there was this man sitting on the sidewalk of a busy street who looks like a homeless and haven't showered for days (the typical homeless look). so i assumed he was a homeless man asking for donations since he was sitting on the side of a busy street at 6 in the morning. 

so me trying to be a little bit generous, i gave him a 10 peso coin. i just put it on the floor in front of him and then leave. 

after a few steps away from him, i noticed that someone just threw something at my head real hard (still hurts til now). turns out it's that big 10 peso coin that i've just gave him. and it's that man! the man who i thought was a homeless man! the man that i was trying to help!

he stood up shouted at me cursing and cursing and said "fuck you" a couple of times and then walks out leaving me there at the middle of the street still shocked from what just happened and all people in the area looking at me like i made a 3 year old in the park cry.

turns out he's not homeless after all. 

i was just trying to help.
