Maybe your title should be 'I'm happy even when your feedback is a slap in the face' ??
Because being critical to be critical - which I have experienced in college, when people would just be trying to make great comments to offend, but actually don't mean anything and have no idea what they're actually saying - that is also not very helpful.
but for the rest, great post!
Good notion -- being critical JUST to be critical is not great. I think I've been a little spoiled with my environments. The worst situation is when you're in a straight-up abusive environment, and the second worst would be a passive aggressive one. I've only found myself in the latter rather than the former. I probably wouldn't like to have either :-D
