It is clear from experience of living in the world, that sometimes the things we say may imply something to someone else that we did not intend it to.
A seemingly harmless comment or even compliment could have different effects on different listeners depending on their personal circumstances, beliefs, etc.
For example - "I wish I could be as skinny as you!" could brighten up the day of a recovering obesity patient, or ruin that of a recovering anorexic.
Or "Oh my God!" may be be considered offensive by a devout christian, but a perfectly innocent exclamation of surprise to another person.
The speaker did not intend any offense, and perhaps is not even aware of the listener's personal circumstances or beliefs at all, but the listener may still be offended or at least find the comment insensitive.
More examples of what I mean can be found here.
But is there a word to describe the process of a listener taking unintended offence at a comment?
Other than 'Taking offence' , obviously.
