I enjoy reading The Post while leisurely enjoying my breakfast, and I like John Kelly’s column as much as anyone. However, the column that described in vivid terms his dog’s proclivity to regurgitate [“For Charlie, it’s a dog-eat-everything world,” Metro, June 17] should have come with a warning. The next time Kelly wants to hurl something similar, I would deeply appreciate The Post advising readers to refrain from eating before, during and after turning to his column.
