A shadow or Remnant . This tune is about Ageism. It just happens. I'm not sure there is a particular age when it cuts in - but getting treated fairly / being patronised or belittled seems to happen at some point.
The lyrics here are those I have not used when this happens - but been tempted to - either sarcastically or in genuine appeal for help .
I think it only gets worse as age descends up us.
