If building bridges is important to you here are 10 ways to start the building

1.Listen wholeheartedly  without interrupting to what someone has to say whether you agree with them or not

2.No matter what the persons viewpoint etc always acknowledge.One could  say for example" I hear you"

3. Find a point of agreement no matter how small in actuality and  or in potential

4. Talk about the issue not the person

5.Describe dont evaluate

6.No matter the temptation dont mock,,devalue,dismiss,downplay etc what someone says ,feels etc

7.Respect  the other in how you speak ,act,react etc

8.Even if you dont feel you are wrong express sorrow for the  tension,hurt,ill feeling ,awkwardness etc created as a result of a specific situation

9.Never say "you are wrong" rather consider saying" The way I see it is..."  "What I have heard is " " From my experience"

10. Ask the other person their view,opinion etc( this does not mean one has to agree with the other)
