Now, since THIS is what you really want, you should make a conscious decision that everything you say or do from now on will move things toward this positive outcome …and furthermore, that everything THEY say or do ALSO becomes an opportunity for you to take things closer to that outcome.
After you’ve imagined what a positive outcome might look like, you should then eliminate your anger, frustration and stress about the situation and feel calm, strong and confident about creating a positive change.
Of course, you would need to be able to do this calmly and confidently because pushing your buttons and getting you to react is what they may be TRYING to do!
If you decide to start civil proceedings, you can contact the Citizens Advice Bureau (please see the link in related information to find your nearest one) or alternatively, inform your local policing team via their non-emergency 101 number.
Where there are threats of violence you should always inform the police and they will treat the matter as a high priority.
Of course, if you are addressing their genuine concern, then they will also become more receptive to a friendlier relationship without the disrespectful language.
If there is really no underlying issue that is bothering them, or at least none that they will divulge to you, and they persist with rude language, you can take the approach of paying them a visit each and every time a rude episode occurs…
You can’t produce a positive outcome if you’re sitting on negative, angry or hostile feelings.
