I give all the time. Not to anyone I know either....and it does benefit me because it declutters my house.
Anyone heard of www.freecycle.org I love it.
Gives people things they need or want and keeps stuff out of the landfills...although probably temporarily...and I get my house decluttered..
I also give money to homeless people....I don't care what they are going to do with the money....they look like they need it and I don't care if its a scam.
I don't know if this is the kind of agape you are talking about...
