i have a question regarding the use of "a". From the dialogue between maria and alex in module 1.3, maria asked alex what he would like to order (boungiorno, preggo?) and alex replied "una pizza con la mozzarella".
From what i understand, una is an feminine indefinite article. When a lady speaks, she would say una casa, for example.
However, from the dialogue in module 1.3, does it mean that a man can use "una" when he is answering/replying a lady? And the same applies to "the" and "an" articles?
Thank you. :)
