Crying in public over a job voluntarily given up

Since giving notice at my job, I have had a couple former board members call me asking why I am leaving. The one I answered today was while in Office Max picking up "Age of Empires" for 11 year old Wilder. This guy is an amazing advocate for history and the museum and always generous with his knowledge and skills. As I was trying to be subtle while talking on the phone in a store, I started crying. Some of the folks I have met in the last eight years have grown on me. It is not just leaving a job, it is kinda like leaving a family. Although without the drunken Thanksgiving stories or embarrassing childhood tales. I told him not to say anything at the board meeting tomorrow, since I didn't want to start crying. He told me it was good to cry, there was something wrong with people who didn't. STILL, I don't want to cry at the board meeting.
Yesterday, another gal gave me a farewell hug and started crying, and so did I.
CRAP.
