I have a feeling that this was a temperature check for him. I do believe that MLCers feel the need to have you somehow reassure them that your not completely givin up on them.
I said just about the same thing on my thread. Sometimes they need some sign from us that we'll still accept them.
There is always little details in real life that don't come through on the posts we put here, so it sounds like you did well by responding how you did.
Interesting link IMP. It depends on the situation when I vent my anger and let it out. I am one of the types that are appalled at extreme outbursts from people. Yet there are times that I wish I was such a person and could just unload. But, can anyone tell me, does a person who has such extreme outbursts of anger actually feel better after the outburst? is there any lingering guilt?
