I'm not sure the op is coming back.
In addition, her second post makes me think she was maybe semi aware there was an issue and was more affronted by the fact she was spoken to about it. She commented that she needed to be more mindful of her body odour in future,
I do wonder when something like this comes up, if people are actually aware when they suffer from body odour issues, can they not smell it, or can they maybe not recognise the extent of it, ie do they think it's not that bad, or maybe they think it's deeply personal and shoild never be remarked on, like weight.
I worked with a man who has significant body odour issues once, it felt like he was unhygienic, for example even his socks were all baggy round the ankles like they hadn't been washed in a long time. People complained, one even asked me not to bring him into his office any more as he couldn't take the smell and it lingered for a long time after. It really was very bad,
I always wondered if he knew and just didn't care enough, or if he genuinely didn't know, or maybe he felt it was less significant than it was. I don't know, it is difficult to understand really.
