My defaults for DU (in case I'm too lazy to post or depressed, etc)
If it's bad news, I'm automatically sympathetic to the victims.
If it's good news for Democrats and President Obama, I say yay.
If it's good news for the country and the vast majority of people, I say that's wonderful.
If it's good news for any DU'er, I say congrats.
If it's bad news for any DU'er, you have my sympathies.
If someone's dying (and I miss the thread), many good vibes.
I guess I could go on but... sometimes I'm just too damn lazy and/or depressed to click and type. True story.
The dying threads just are the hardest for me. I usually don't know the people, and I don't what to say really. 
The "please help me, I need a donation" threads are the second hardest - I wish I was a billionaire but alas I'm not 
I also have a son I'm still getting "launched" into the adult world, so to speak.
Anyway....that's me.

I try to live up to what you outline above, I think I get by. I miss having higher income and being able to chip in to every request some little amount.
Thank you for wishing me well after my head surgeries, too!
You're also one of the best, sincerely. I'm very glad your surgeries have gone well, and hopefully no more!!!!!!!! Are the doctors optimistic about that ? 
Doctors seem optimistic and, even better, sincerely sorry that it ever became infected and required so much extra work.
I love all the staff and it's funny being on a first name and hugging basis with doctors at one of the world's best neuroscience hospitals.
I am truly blessed, lucky to have recovered so well and to have had the best doctors.
All on ObamaCare.
It's not what we need aka single payer, but it's a step forward. I'm really glad it helped you! Now you have a pre-existing condition (I guess ?) and if you changed insurance companies, under the old scheme it would be a major problem. Not any more.
All the best to you.
