Like most of us, Barbara Bush likes to keep up with her college girlfriends. The former First Lady of the United States wrote a dispatch for the Smith College alumni magazine, where she told her classmates that she is still in love and "still old".

Back when she was Barbara Pierce, she attended Charleston's Ashley Hall boarding school. When she was 16, she attended a Christmas dance, she met a young man named George H.W. Bush, who was a senior at Phillips Academy in Andover, Massachusetts. They fell in love and were engaged a year and a half later. Bush joined the Navy, though, and Pierce enrolled at Smith College. (Fun fact: Nancy Reagan graduated from the same college in 1943.)

When Bush returned on leave, Pierce left Smith College to get married and become Barbara Bush. The college awarded her an honorary degree in 1989. Bush clearly looks back fondly at her time at the Massachusetts school, as The Boston Globe reports she has sent her alma mater updates on her life, dating back to 1953 when it reported that her second son, Jeb, had been born.

In her recent note, which was included in the "Alumnae Lives Update" section for the Class of 1947 in the Smith Alumnae Quarterly's latest edition, Bush hilariously noted that she was "still old", was "very proud" of her 17 grandchildren and her children who are all "serving others in their own way", and that she is very much "still in love with the man [she] married 72 years ago." In the magazine, she wrote, "George Bush has given me the world. He is the best — thoughtful and loving."

The Bushes have the longest marriage of any U.S. president, with Jimmy and Rosalynn Carter coming in a close second, as they will celebrate 72 years of marriage in July. Until these Southerners came along, the record for longest running presidential marriage was held by John and Abigail Adams, who were married for 54 years back in the 1700s.
