I'm not going to be sympathetic about a lost/stolen purse
Why won't you be sympathetic about the purse?
I have a purse that's been lost or stolen before and it was the most horrible experience ever.
I'm sorry you went through that, I had a similar experience as well. We don't have to be too concerned over what happens to others, especially if we don't know it. Our own mental health is important to take care of.
You're right, I don't even like thinking about it.
It's fine if you don't want to offer sympathy if it would be too difficult for you. It's good to take care of yourself and your own feelings, first.
