I usually like animals better than people. But I admit there is hope for humankind still
A friend of mine once found a note on the front door of the apartment complex where he lived: "The old lady from the 4th floor has lost 20 lv (the Bulgarian currency) this morning. Her pension is only 160 lv, so please, whoever finds her money, return them. Thank you!"
So my friend went to her apartment and rang the doorbell. A nice old lady opened up and seeing the 20 in his hand smiled, gave him a hug and refused to take the money. Apparently he was the sixth person to have "found" them.
So yeah, there is still hope.
