It’s so very important to accept and respect bounderies of those around you. Even those of strangers. You shouldn’t even be asked to do so. They are there for a reason. A deeply grounded reason, not even neccessarily for you to understand. But when you are asked to respect a certain boundary, even when it comes with an explanation of how and why, there should be some form of acceptance.
Asked not even once, but twice. Explained not even once, but twice. Don’t all parent teach their children to respect each other? When you are not able to accept, you should at least respect. Respect the self-ownership of the thoughts and actions of others. Respect their personal space and their private life.
I do not ask much. Especially from strangers. I ask nothing but to be treated with respect. As does every single human being on this planet.
