I know it is slightly 'off topic'. but this brings to mind, my besties eldest son. I had known him, literally from the day he was born (that how his Mum and I met some fortyplus years previously ). He was pretty well-off being a trader and probably not the most ethical even of these!!! My friend had told me of the language he used to her (the same as these people do at their work). I was quite horrified- no way would any of my children ever have sworn in any way in front of me, let alone directed at me.
One day he was at her house when i was visiting, and I actually heard this going on. Language was very, very insulting. Suddenly, he turned, and noticed me standing there and immediately said ' Oh, Sorry Aunt......'. I did point out that the person he should be apologising to was his Mum!!!
Anger management!!! Help needed.
