"A" vs "An" ....grammar trivia

[Gracefulsarah]

I understand about the directions of the quotation marks when writing, and that's how I do it. But on my keyboard there is only one " straight up and down.

I have another question about quotation marks. I always use ". When (or would you ever) use ' as quotation marks??

You would use ' when quoting someone who was quoting someone else. For example:

Billy said "That guy was really angry and he yelled 'Get out!' then he ran down the street."
