I go shopping to Florence tomorrow afternoon

I go shopping in Florence tomorrow, or if you are my wife, Andrò a fare la spesa a Firenze domani.

I don't understand this part of your reply:

...or if you are my wife, Andrò a fare la spesa a Firenze domani.

Would you please explain it further?

By the way, in Italian, we use the present simple/simple present (presente) to express the above concept, that is, 'Vado a fare la spesa/a fare shopping a Firenze domani'.

Thanks again for the help.

Sorry, I asked her to translate "I will go shopping in Firenze tomorrow". You are right about the simple present. She is a language student. She has learned French, Spanish and Italian, and is now studying Catalan.
