I had this conversation with a few friends a couple times.
You see, I write fanfiction in fanfiction.net. There were several times when my readers would review and left me messages on my grammatical mistakes.
I told my friends how I feel about my English level when my current beta approached me and volunteered to be my beta.
And this is how they reacted:
A: Why would they say that? Is their grammar really that good? Well... just ignore them. I think your English is pretty good.B: Ignore them. As long as it (your English) sounds good (when you speak them). It's okay.C: Let's register for English class! (When I told this to my mom, she said: Why would you want to study English? Practice more on speaking. You'll improve.)
They're missing the point. I was really devastated knowing that I haven't improve much in this matter. It's sad... Especially when you knew that your beta (or editor) is a lot more younger than you.
My only regret is that I don't pay much attention in English class... (ＴεＴ；）
