Each morning the tone for the day can be set with the most subtle of cues. If I greet the tall one first- before he greets me, it generally doesn't end well.
If I'm patient and don't even look at him till he says something to me, I know the day will be ok.
This morning in the group home I walked passed him and I was greeted with a "good morning Knucklehead". This is nearly as loving as it gets from him. Some times I get "hot sausage" or "vanity fair" (don't ask) on a good day... more often than not I'm showered with swearing.
This morning I turned to him and asked "how do I get rid of my title of Knucklehead?"
Without missing a beat he responded "stop working here".
