This type of boundary refers to your thoughts and ideas. Healthy mental boundaries include respect for the thoughts of others. This means that your ideas should not be shut down or belittled. If they are, your boundary is being crossed. This type of boundary also includes the ability to consider whether or not it’s the right time for a discussion. Examples include: “It hurts me when you put down my ideas.” “I think we should avoid this topic for now. Let’s talk about it another time.” “I respect that we have different opinions on this topic.”
