Army Veteran Dick Hauck's Love Letter To Wife Delivered 60 Years Later (VIDEO)

At 21 years old, Dick Hauck knew he had found the love of his life, and he was eager to let his girlfriend know it.

Hauck, who was serving in the Army at the time, wrote Arlene a detailed love note that revealed he had purchased an engagement ring, KARE 11 reports. Arlene never received the message, but that didn't stop the couple from tying the knot when Hauck returned home.

In March, nearly 60 years later, the letter finally made it into the hands of its intended recipient, thanks to a pair of workers remodeling Arlene's childhood home who found the unopened letter behind some linoleum, KARE 11 reports.

And when Dick read through his own words, he couldn't help but tear up a bit.

The Hauck's love story is reminiscent of New Jersey couple, who, after 71 years of marriage, still remain head over heels for one another.
