Performance Review questions

I definitely agree that happiness is important to me, my coworkers, and to thoughtbot. I want to be happy, I want my coworkers to be happy, and I believe thoughtbot wants us to be happy as well. 

But my sense is that the company environment enables each person to raise issues that are making them unhappy. I'm not sure that I should be speaking for someone else in the review - they should instead (ideally) feel comfortable asking about something when they're unhappy. If someone on my project takes me aside and talks to me about something I'm doing that makes them unhappy, I will definitely fix that. If I see that my behavior is making someone else unhappy, I will definitely fix that. Those are all things that I can fix, though, not things that the other person could fix.

But I'm just not sure that I'll always notice when someone's unhappy. I'm having a hard time coming up with even an example sentence of feedback I could give for this question.
