Wanna be more arrogant? Some people are dyslexic or just struggle with stuff like that ''Try harder'' isn't as easy for them as it ,apparently, is for you.

What if Luckypinch struggles with English and tries her best?? Are you helping her in any way?
Or what if she hasn't got English as a first language? English is one of the most difficult languages to learn. You try learning another language.
