Bathroom doors are great. Let&#x27;s not confound surveillance of interactions and privacy in the extreme sense.<p>Bathroom doors allow you to interact with yourself with <i>some</i> level of privacy. People know you&#x27;re in there. They know for how long. They know if there are extreme sounds or scents. If you misuse the plumbing or other bathroom features there is clear evidence of this. In rare circumstances, the bathroom door can be kicked down while someone is using the bathroom.<p>The most common result of such information is &quot;are you ok darling?&quot;.<p>Bathroom behaviours are interesting because they provide a real case study on the impact of acceptance on privacy. On a first date, where you&#x27;re not presenting the real version of yourself, you don&#x27;t want the other party on the date to know anything about the events while you&#x27;re in the bathroom. Over time, if the relationship progresses, the secrecy around these events changes. The reason for this secrecy changing, I believe, is trust&#x2F;acceptance. Over time you know that if the other person learns more about the bathroom events, it will not change how they perceive you. If you&#x27;re in such a relationship, it also doesn&#x27;t mean you wont use a bathroom door, and it doesn&#x27;t mean you don&#x27;t want your partner to use one.<p>Hopefully that analogy makes sense. Most privacy advocates have a list of &#x27;secrets&#x27; they fear will be used against them. I think we&#x27;re more likely to see a world where this fear is addressed through improved respect of differences, compared to a world where suddenly surveillance is effectively impossible.
