You may think that you don't need to worry about actually learning the grammar rules because spell check and grammar check will come to your rescue. And I get it: spell check and grammar check are great. Every time I spot a red or green line in my writing, I check it out, and many times, although I hate to admit it, I have made a mistake. But spell check and grammar check are like vodka: they are definitely helpful but shouldn't be solely relied on to solve our problems.
