Sam S, my assistant programmer, can always be found
hard at work in his cubicle. Sam works independently, without
wasting company time talking to colleagues. Sam never
thinks twice about assisting fellow employees, and he always
finishes given assignments on time. Often Sam takes extended
measures to complete his work, sometimes skipping
coffee breaks. Sam is an individual who has absolutely no
vanity in spite of his high accomplishments and profound
knowledge in his field. I firmly believe that Sam can be
classed as a high-calibre employee, the type which cannot be
dispensed with. Consequently, I duly recommend that Sam be
promoted to executive management, and a proposal will be
executed as soon as possible.

Project Leader

Sam S was reading over my shoulder while I wrote the report sent to you earlier today. Kindly read only the odd numbered lines [1, 3, 5, etc.] for my true assessment of his ability.
