qualify for an advance parole

In the I-131 instruction:

"Advance parole is an extraordinary measure used sparingly to bring an otherwise inadmissible alien to the United States for a temporary period of time due to a compelling emergency. Advance parole cannot be used to circumvent the normal visa issuing procedures and is not a means to bypass delays in visa issuance."

If I mention: "I plan to travel outside of USA for family reunion" in the I-131 cover letter, do you think I will got denied because this reason is not "compelling emergency" at all?

How will you ""On a separate sheet(s) of paper, please explain how you qualify for an advance parole document and what circumstances warrant issuance of dvance parole." ?

Thanks
