I am sorry about that because I am afraid to give others wrong suggestions.
^How can there be a wrong suggestion?
A suggestion is a suggestion, and it is up to the person who receives the suggestion to determine whether it is wrong or right. Also, on this site, if people disagree with your suggestions, people can, and will, comment and offer their opinions.
Now that you know, perhaps you can go back and give detailed suggestions, and make your feedback on other people's essays as detailed as the feedback you would like on your own.
