You know what, Pao? He probably sees you both ways, and it probably depends a lot on his mood or frame of mind. That's how we all are. When I'm angry at someone I love I don't think about them the same way as when we're at peace or when I'm feeling very loving toward them. Each of us is a spectrum, too, so I'm sure there are times you aren't at your best, and times you are, and a whole range of states in between the extremes of the Queen of Pents.
The thing is, though, that how others see us isn't important in the long run. It's how we are and how we know ourselves to be that is, because that's what we have to work with on a day to day basis. Others are rarely clear about who we really are. I've been married 25-1/2 years, and we still surprise each other with the things we reveal about ourselves over time. Everyone is more complex than a statement such as "you're lazy" or "you're not using all your talents."
Then again, we ALL want to feel loved and cared for, so we place a lot of importance on what others that we care about have to say about us.
But -- and this is off-topic -- one of the wisest things I think I've ever heard is some advice I got in a class on dealing with difficult people in the workplace. That's that when someone confronts us with what feels insulting, a good thing to say silently to one's self regarding that person is:
"What you think about me is none of my business."
I think that's wise because we all have positive and negative thoughts about others that are private thoughts. Sometimes when we're upset they leak out, but what leaks out is never the whole complicated spectrum of what we think about that person. And we don't know everything about that person anyway. Those words are just what surfaced in that moment, and they're more about the person saying them than they are about the person they're said to.
I agree with others that what you really need is to ask another question. Rather than asking how he sees you, try a check-in with yourself as regards work, a "How am I doing in my work life?" reading. And if he's someone close enough, maybe you could also read about "What I need to know about how he's feeling about himself." If he really wants another job and has been looking and not finding, that in itself can be quite a self-esteem bruiser. With the world economy as it is, job markets are tight everywhere. It's not a good time for anyone to be looking for a job. So maybe he was just lashing out at someone he felt safe with -- you.
(ETA: Besides, so what if someone isn't using all their talents in their job? Who among us ever does? I have a relative who has a masters in French lit and works as a police sergeant. She loves her job, and she's helping people everyday. Many of my greatest talents weren't marketable at all when I was in the job market. So did I want to be a starving artist or someone making a good living doing something else and art as a serious hobby? Personally, I'd rather not starve.)
