Female relative lost her job last year and got another one after lots of blood, sweat and tears. She's been through a lot this past year, illness etc. Don't want to be too detailed through fear of being outed.
Anyway, when she told me I said 'How many hours is it?' she said it was only 15 but OK for now. I thought all was fine but apparently I have now upset her and made her feel judged. Apparently I was not happy for her and her achievement got downplayed. 
Aibu to say this is oversensitive? I am pleased for her but do feel the job is not ideal and she can do better.
