To Err Is Human...just Cross It And Move On

I remember then in primary school when I started using biro,if there is any error I try to erase it using chalk n d error reappears. There was a time I started using my saliva which leaves a hole in my book n makes it look dirty,teachers will reprimand me,calling me dirty but there was a particular teacher that told me that if there is any error I should just cross it instead of trying to make my book look messier. I argued that I don't want people to laugh at me if my error is seen, he said it's better to cross it than for me to create more errors in an attempt to cover up the first one...in life,anytime u make a mistake do not try to cover or erase it,just cross it over so as to avoid making it look messier.
