Why some people don't follows the basics!?

Re: Why some people don’t follows the basics!?

I think it’s more to do with upbringing. I remember been in the school canteen, we had the same education and lived in the same area but I swear the eating sounds that people made, you would think they were raised by wolves.
I always remember my parents telling us to eat with our mouths closed and not ‘smack’ your lips while eating.
