'Sanity Fund'

So at the pre-deployment meeting my husband's boat hosted a few weeks back they talked bout the "sanity fund."  I was intrigued when I heard it because I wasn't really sure what that fund was for.  Apparently it's a fund for wives/girlfriends to use while their significant others are away.  Let's face it, when your partner is gone, you get lonely and bored.  The only way to keep busy is to either go out or find a hobby, which usually results in money being spent.  I told myself I would save money while my husband was away, but I found myself making little purchases here and there.  Whoever thought of this fund is genius.  Although I have bought a few things, I'm proud of myself for not spending more.
