Re: Transportation class?
Also, asking for help. I recently rode public transport in an unfamiliar city and I could barely understand the station announcements. I had to ask another rider what was just said and for confirmation that I had not missed my stop. (I agree that we don't make casual conversation with our co-riders, but most people are kind if you have a request for help.)
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
