Not everyone can empathize appropriately though in different scenarios. So, in effect some people just do their best and follow the other person's lead.

Here is a way to consider what "loss" can mean to someone. If you have something you get used to using everyday, like your cell phone for example, if you suddenly lost that you would get upset am I right? Well, the human brain is like that where a person gets used to having a person in their life all the time and when that person is no longer there they have to get used to no longer having that person around and there is no way they can replace that either. The brain has a hard time adjusting to suddenly losing something that a person is so used to having around them. While you don't form emotional attachments, your brain can still struggle suddenly not having something you are so used to having in your life. So, in effect you can still feel discomfort even if its not one that also contains a lot of emotional loss as well. What would you experience if you used your cell phone constantly, it was important to how you lived your life and you suddenly lose it and there is no way you can get another one. It would mean you would have to learn to live your life very differently. How would that affect you? I am just trying to think of something you really worked your life around and then you suddenly lose it how that might affect you.
