My local hospice offers bereavement support
There are 56. Each has a minimum of 3 client load. They have an 8 month waiting list.
That is how many people who require support with "normal grief," and this is just one area of the UK.
I disagree with you that simply because some have sought out the colleague to help, it means its empathy. For some, it will be sympathy, and for some, it will have to do with other more complex things like their mental programming.
It would be lovely to think we all naturally know how to be emphatic, but even if that was the case, this would need to be a learned skill from our upbringing. I'm aware this is not what you mean. I am merely pointing out that we are not born knowing how to express our empathy. Some humans will not develop that ability. I do agree that it is a natural human emotion.
If you read the first post OP also states that the bereaved person "She is in an awful state As you can imagine, people have flocked round to help and offer real life support " this is clearly something Op and friends have been happy to provide. However, this doesn't paint an image of it only having been mentioned once. And as I said in another post. Op likes her bereaved colleague she does not like the 24 year old calling her a knobhead. We are not getting an unbiased assessment of the situation.
Due to this, a lot of what is coming across as empathy here may well be sympathy.
We simply won't know until we hear what the 24 year olds view is, and we are unlikely to get this.
