How can I set my file to not pull in the headers in my csv file? I have tried this:

```
CSV.foreach(email_response_file, :col_sep => "\t", :return_headers => false) do |column|
  ....
end

```

However, regardless of whether I set `:return_headers` to true or false I still pull in the headers. How can I get rid of them? I assume my issue is the `.foreach` method I am using.
