   Format: MarkdownItex> why so careless Not at all, I spent about half a day for just several edits (in the middle of exam periods and having almost no sleep in between), as I check the literature, think of formulations and so on. Different people see different aspects, miss different aspects and easily correct different aspects. My native language has no articles and I will be always missing them often for example.
