Yes, I am feeling like this about my T at the moment. Making comparisons about how she excels in her work and how hard she works and how much she achieves. I don't come out well in this comparison! It's got to the point where I am actively avoiding hearing about her work, whereas there are times when I'm quite interested and it's quite helpful.

T says the comparisons aren't helpful because we're at different stages in our careers, but that doesn't help me because I play the 'when T was my age...' game. I come out even worse from that

I have also felt overwhelmingly resentful of 'T's perfect life' (rather than 'perfect T') at other times. I asked her to please tell me one thing that was wrong with her life. I said it had to be a BIG thing! She said she wished she hadn't bought this particular house as it caused nothing but problems. (My reaction was to think 'at least you could bloody buy a house! And in such a sought-after area!'. But I kept quiet, because it seemed a bit self-defeating to ask T to tell me one of her problems and then tell her that wasn't even a real problem).
