How about kind? You've written posts to me that were really supportive and understanding and I've seen similar posts you've written to other people. If you weren't kind and generous of your time you wouldn't bother.

I hate that feeling of being stuck. It's really, really horrible I'm in post-t hangover mode so can't think of anything insightful to say right now but wanted to let you know there are good things about you. I barely even know you and I've seen them!
