People will not respect you unless you demand them to and stop them when they cross your boundary. People will not know how to treat you until you tell them how you allow yourself to be treated, yes some people are pushers and we have to use our voice to speak up and express how we want to be respected. If any connection does not have any sense of respect, those connections are doomed to be heavy on one sided, where there will be no equality. Respect is a Sense of Balance Exchange and Equal interaction.
Being Aware of when and how people are disrespecting you and taking action to make a decision to speak up and express and reject a certain value that is imposed on your boundary that you do not happily accept is the best way to begin putting boundaries in your life where people will know how to treat you and how you give off the vibe that you are not a doormat or a pushover to simply be pushed around and stepped all over. So you have your sense of dignity intact and realize that other people cannot treat you otherwise.
