I stand on this. If you're looking for clout, was your deed genuine? If the person never recognizes you, are you going to stop doing good for others just because you won't get praise? You shouldn't, but everyone's different. I would be lying if I said I didn't want praise for doing something good for someone, but as I've gotten older, I learned that some people will never shout you out for doing good for them, so move on.
