It's taken me quite few years but I have gotten to the point where when people get like that with me I just look at them.
I got chewed out unnecessarily yesterday. This woman went all nutso over what should have really been a yes or no question - either she could do it or she couldn't
I just stood there and watched her thinking, "Wow, you must be one very stressed out, insecure person to act this way and what you really need is chocolate and chickens!"
BY that point I start to smile because my chickens always make me smile and she got madder and madder while I just stood there and smiled!
Later I dropped a candy bar on her desk and said you should get some chickens!
People came up to me all afternoon telling me how out of line she was and how impressed they were with my brining her candy!
(I can't always pull this off!
I get mad too..... But it is great when I manage it!)
