I befriend you and get you to trust me.
After spending the rest of our lives with a close friendship, I meet you on your deathbed.
As you lie there, telling me of your dreams you had and those you achieved, I listen and shed a tear.
You pass away that night. I have truly lost a friend, and at the age that I too have not long left on this earth.
It saddens me to see my life ending so soon, however, you left me a diamond in your will and I have completed my task.
Sucker.
