Rhinos do make mistakes, and not all of them can get patched up. Sometimes We feel victimized. Sometimes it just feels like We are embroiled over a misunderstanding.
Anyhow, Regrets are a sticky business. We apologize, but there is often a bad aftertaste. We feel wronged.
All a Rhino can do is press on, and hope Bad Feelings will fade, the sooner the better. For everyone concerned.
