We've had the same cleaner for 5 years - reliable and does a pretty good job. No concerns about their work.
However every week we seem them they look increasingly jaundiced. Today was just alarming, really really yellow. They rarely mention their health but do talk about other personal issues and we have a good relationship generally.
WIBU to ask after their health? Or even mention I've noticed they are jaundiced? I'm genuinely worried rather than being nosey.
