I volunteer to help my university write a journal in a website. After spending hours on paragraphs I found a visitor to leave a note. He told me to edit one of the paragraphs as instructed. This guy has disguised himself to be several different visitors to make me follow. So he finally managed to change it. I didn't bother to ask him for assistance. No one in the group knows this anonymous person. Plus, ooks like an unhappy person in life I don't want to deal with. it's not his job to judge my work and he knows nothing about it. He l What should I say in a polite manner to get him out of my way, please? I couldn't figure out what a native speaker would say in this scenario. ( I know only in my native language!) Thanks in advance.
