Cheer up on the frequency.
On my flight recently I had first a controller who was under training which I could tell by the voice which is fine and I try not to make his life difficult but then I changed frequency and was greeted by Mr clip and grumpy where you get the feeling you personally are to blame his life has gone to pot.So I was glad to change frequency again to be greeted by a chap who made me immediately feel that was in safe hands and he would fulfill every wish I might have.
I don't expect you all being so sweet, I don't really know what is troubling you at the time when I am passing, but how about cheering up a tad.
I am myself am guilty of getting ecited on the radio every now and then therefore I am trying to reduce those instances.
