SOMEONE-EXPLAIN-WHY-THEY'RE-DOING-THIS-TO-ME

Yesterday, a new co-worker asked me during lunch break what my story was. She said she’d found out everyone else’s story and wanted to know mine. I was so confused by the question and responded with, what do you mean? I don’t have a story. I was born. Here I am. The end. Apparently everyone has a story and she went on to explain, e.g. did I have a partner, married, kids, was I born here, etc. Firstly, for someone I’d only worked alongside with for three days, this was a personal question to ask. Secondly, I still don’t get her question, so I answered her questions: I was born here, I am single and I work as a pharmacist. Thirdly, this is not how I share my personal life with people. How do you explain ‘your story’ to people in a few minutes? Especially to a stranger :\
