Don't you just hate it when people put pens or pencils in their mouth? I know it's subconscious but I still find it horrible so I have an old pot with old scruffy pens and pencils in it so that when people come in and need to write stuff down, I give them an old pen or pencil. My nice stuff is out of reach to visitors!
Oh yes GC I forgot to mention my ladybird drawing pins I only use them in my office, if I put them on the noticeboard outside in the corridor they would disappear!
