It feels hurtful for the OP to see an article that is seemingly written about her in a rather unflattering light.
There is then the whole issue of hugging relatives and whether or not you should or not.
My mum likes her grandchildren to say goodbye to her (making eye contact) and give her a hug. She is in her late 80s and that is what she thinks is polite. My kids aren't wild about it, but they appreciate that in her eyes this is good manners and they've just eaten her food and out of respect & courtesy towards her, they do it.
They also know that they aren't about to start hugging random strangers or anyone who might be slightly worse for the odd shandy or two and who fancies a grope!
I'm all for people believing that they are the boss of their body, mind and speech - but just how far do we go with this? Is it ok for people to be rude and not say thank you, just because they don't feel like it? Is it ok not to stand up in the classroom when the teacher asks you too because it is your body and you don't want to do that with it? Is it ok not to take part in PE for the same reasons? Is it ok to run out into the road just because that's where your body feels like it should be?
There are lots of occasions when we can't be the absolute boss of what we do or say. Sometimes I'm sitting in a long meeting and I want to lie on the floor or yawn out loud because I'm so bored - that's what my body wants to do BUT that would be disrespectful to my colleagues, so I don't do it.
I think politely hugging a relative is a compromise that may help children differentiate between where it is absolutely critical that they are the boss of their own body and the times when they need to compromise slightly and think about how they make other people feel.
