The people you love are the closest to you. This means that they've seen you at your best and at your worst. You might take for granted that they'll always be there, but it's possible to push them away with rude behavior. To stop distancing yourself from those who care, learn to monitor your actions and habits. Everyone you love will thank you for it in the end.
Sit down with loved ones and take ownership of your rude behavior. During this chat, it's important to listen as much, if not more, than you speak. Your rude behavior affects the others just as much as it affects you so you should be open to hearing about it.
Plan out a series of small changes that you can make every day. You want to focus on one change for a set amount of time until it becomes a habit. Take your time with this and don't expect a complete personality overhaul in a day or even a week. Some habits to consider are listening before you speak, saying please and thank you to your children, and giving others the benefit of the doubt.
Limit the amount of rudeness that you display in public and then work on what you do at home to the people you love. This includes yelling at loved ones, embarrassing them on purpose, and any other manner of disrespect. Gradually, you'll start to notice your own negative emotions before they trigger rude actions.
Treat the people who love you they way you would like to be treated. As mundane as this sounds, it's important for maintaining mutual, loving relationships. Before you let your sour attitude ruin a moment, ask yourself how you'd like to be treated if things were the other way around.
