One day a lady went for lunch and there was a guy lying face down right in front of the gate of the office building. The sign says: homeless, nothing good, mental illness...

The lady felt bad for the poor guy on the chilly ground, probably hungry as well; so she purchased one more sandwich for him. On her way back she bent down and offered the food. The guy raised his head from the ground, looked at her and reached out his right hand...

and he grabbed the board of sign and hit her with anger, then put his head down again

The shocked lady backed off, read the rest of the sign. It says:

...I spot for $20. otherwise "F" off and leave me alone...

That's the punishment of not showing enough attention/respect to other people, and not reading things completely...

The lady learnt the lesson. She came back to the office  and prayed for him, for what he really needs.
