There is one other reason for dressing well, namely that dogs respect it, and will not attack you in good clothes.
I’ve changed, and she’s changed, but we haven’t changed together. We were in separate dressing rooms the whole time we dated.
When we fail to set boundaries and hold people accountable, we feel used and mistreated. This is why we sometimes attack who they are, which is far more hurtful than addressing a behavior or a choice.
Dressing up is inevitably a substitute for good ideas. It is no coincidence that technically inept business types are known as "suits."
