I've got a lovely friend (A) who had a really awful childhood but has worked very hard over the last few years and is now in a very comfortable position with her career. Another friend (B) is in the same industry as A but has not been so successful. B is always banging on about how 'lucky' and 'fortunate' A has been.
A is very modest and never stands up for herself over how hard she has worked and usually just goes along with what B says. A maintains that luck has played a big part in helping her escape her background. However, B has been very privileged (albeit not very motivated) and I hate seeing her chipping away at A's confidence by constantly attributing all of her success to luck.
AIBU to think it is rude to tell someone that all of their achievements are due to luck? Clearly luck plays a part in everybody's lives but the continual references seem to belittle personal successes.
