In Nouns^x, Conditionals^x, Difference between^x

I obviously agree with Forbes: it depends on your first language. I have never had any problems with passive sentences, subjects and objects, the difference between countable and uncountable, etc. because those are all features I have in Italian too. It is not difficult at all for me to use...

Scenario: I was going to buy two computers last week at my work place but I didn't. And someone says: Why didn't you buy those better?? Because I never bought the products and I didn't do any returns? This is conditional #2 (Present Imaginary), does it mean returning products in general is bad?...
