The greatest compliment one can receive, simply, is to be loved. No special gifts needed, no money involved, no pretensions, just love. Thus, if you see someone who you think might not be having a particularly great time at the moment because of economic circumstances or health issues or whatever else, all you have to do is show that you care. Give emotional support or even just a kind word. And you'll see, love conquers all.
Love is the greatest compliment
