You are right. "Were" would be the most proper way to say the sentence, as it follows the subjunctive and it is a hypothesis. However, colloquially, I think he was simply trying to emphasize the first "is" through saying it again.

Definitely agree with Peachey. Both are impolite, however, the latter is a bit sassy in tone and often is said to make a point (i.e. "I couldn't care less if Mary came to my wedding or not.")

My experience learning English (Correct me, please)

 

I've been studying English for four years.  But I must confess:  I didn't study .  I know the basics (or fundamentals) of reading and writing, however, I feel insecure when having a conversation with a native face-to-face.  When I began using iTalki, I decided that I would dedicate myself to improving my English.  Though I do not have time to practice every day, I'd like to use each free moment I have to practice the language with natives.  My main issue is that I'm very shy.  I think this is the reason that's barring me from improving my speaking skills.

 

Hi, Tamires.  I think your English is great.  Here's a correction I wrote up for you.  I think most of the areas you're stumbling on are verb usage and colloquial phrases.  Keep up the good work!
