My worst elder experience.....Mmmmmm.  Well I would have to say the day a local need part was given regarding Df'd people.  Me and my hubby where the only Df'd people at the hall so it was about us.  He called us "Evil" said not to make eye contact with us or they would quote "be sharing in our evilness!" 
 
At this point I still believed it was the "truth" and I wanted to rip the old bastard off the stage and beat him to death with my bible!
 
Did that sound EVIL
