If you were applying for a job, you would like for your resume to be eye-catching. The same should be the case when sending shiduchim resumes. The boys (parents) in today’s Jewish world get flooded with resumes. Do you think the boy’s parents will call every reference on every resume? These paragraphs often help the resume reader decide if it is worth his time to even call the references. This also means that these paragraph should not be just vague generalities thrown down as these words won’t have the desired effect on the reader.
Good luck with your search.
