President Thomas S. Monson, in his talk entitled "See Others As They May Become", told the men in Priesthood session of LDS General Conference that every woman deserves to be told she's beautiful.
The young men in the priesthood have taken his message to heart and created this video as a dedication to the girls and women in their lives.
Here is the entirety of President Monson's talk:
The Book of Mormon is a volume of holy scripture comparable to the Bible and is a record of God's dealings with His chosen people in the New World. The main purpose of the Book of Mormon is "to the convincing of Jew and Gentile that JESUS is the CHRIST, the ETERNAL GOD, manifesting himself unto all nations." (Book of Mormon Title Page) It was written by ancient American prophets for our day (Mormon 8:35) and is an American testament of the Lord Jesus Christ.
