Speaking of, [...] or Verbing, [...]?
I started out wondering if there was any Spanish analogy to the English construction `Speaking of, [independent clause]` as in >Speaking of potatoes, I love them. The most obvious possibility is >Hablando de las papas, las amo. but to my (untrained) ear this sounds weird. ____ Then I realized that in English, the construction `Verbing, [independent clause]` is more widespread. For example, >Walking to the post office, I saw John. In Spanish could this be >Caminando a la oficina de correos, vi a John. or would you have to say something like >Mientras estaba caminando a la oficina de correos, vi a John. ? More importantly, *is this natural? Do people actually talk like this?*
