There are some lovely people in my life I wouldn't begrudge anything. If they got a lucky break or achieved something, I'd think 'good for them, they really deserve it'.
However I have one acquaintance who is queen of, at best, the humble brag, and at worst, the all out brag. When she got a recent promotion she smugly informed us all that she would never settle for earning anything less than her age (e.g. 30 - 30k) thus making sure we knew exactly what her new salary was). When discussing her wedding plans in the presence of another bride-to-be who notoriously struggles with her weight, she smugly announced that she didn't even have to try to lose weight, it was 'just falling off'. And when running a sub-hour 10k on her first try she innocently pipes up: 'oh, is that fast? I didn't even know.'
I find myself begrudging her successes where I would never begrudge those of others, and it makes me feel I'm being brought down to her level.
How do you tame the green-eyed monster in these situations?
