lets keep this useful thread alive!
what exact difference between "we HAVE HAD a terrible examinatior" and "we HAD HAVE a terrible examination"?
it depends on if the exam is for a colonoscopy or a sigmoidoscopy.
colonoscopy and sigmoidoscopy sound pretty same, not sure i ever be able write them correctly, good thing im not a doctor, so i will use "ass inspection" for these both terms
