Yes, indubitably! Yes. No.
Just plain bad, lazy speech, grammar & spelling gives me the sterks in any given situation! It's appalling the extremely low level 'out there' in tv, media & average 'Aussie' land.
I correct people, purely from a sense of helping them, & maybe others' at the same time. At NO time am I trying to be a 'smartarse'. As a Trainer in my career, I was motivated by wanting to help people obtain the knowledge I had, & prosper in their workplace.
The study of 'ENGLISH' was NEVER difficult for me. I was blessed by very sensible parents' who read to me from year dot, & in turn, listened to me read. My Mother was a former School Teacher. When it became 'my time' to become a Mum, I read to my child/ren from the moment I knew I was pregnant. The Editorial of the daily paper was a 'set piece', so my children learnt, from a VERY early age, 'Current Affairs'!
I topped EVERY English exam. I did from Grade 1 to Grade 12, inclusive, & beyond. I absorbed EVERYTHING about it like a 'sponge'. I'm still studying it, through various avenues, as I just L O V E the mechanics of our language.
I know it's supposedly THE hardest language to learn for persons' not raised in an ENGLISH speaking country. They've just GOT to persevere, if the want to have a good life, in such a country.
