This is petty, but it bothers me that John McCain addresses people generally as "my friends."
I've never even met you! You are not my friend and I am not yours. I'm disappointed that you would take friendship so lightly as to apply it toward complete strangers.
(Note: This is not a political statement nor an endorsement or condemnation of either presidential candidate. It's just something that has become a peeve of mine as I've continued to watch events unfold this election season.)
