Straif is sulphur: the reagent that changes what it touches and is not the point itself. This week you are the catalyst rather than the outcome, or somebody near you is. Something is transformed by contact with a thing that will not itself be transformed. That is a useful position and an easily resented one, because the reagent rarely gets named in the description of the result. Do the work of altering the situation, and set your expectations about recognition accordingly, since sulphur is remembered by its smell rather than by the metal it made possible.
