If my place asked me they'd get told to go **** themselves. My profile is also set to private & I'm very anal about the permissions. I've even gone as far to set-up different "lists" that have different permission settings.
Including the "Work" list that is set to show people absolutely nothing

. I don't actively add people on FB from work or many other places really so when I get a request I just dump them into the purgatory that is the "work" list & claim I never use FB

.
I also make it a habit of going through my wall deleting my old posts every so often, i think there maybe something wrong with me..
