<human>: Can you provide a brief rundown of the text in within 3 sentences?

Right of the bat, I told her no. 

She's a little upset with me now. She keeps telling me that people getting caught for identity theft doesn't happen that often and all this stuff. IMHO, I was no angel when I was underage. I snuck out and went to house parties and stuff. I never had a fake ID or borrowed someone's ID. No real reason why I just didn't. Even when all my friends turned legal in university I still didn't get one. Mostly because of sheer laziness to go out and find one. 

My sister and I have a really good relationship. After I left for university that bond got stronger. In her senior year of High School she started to ask me to borrow my ID. I told her no, because I kind of need my ID for you know.. life things. She moved to the other side of the country and is in her first year of uni. She asked to buy my ID of me for her to keep so she can go out with her friends and wants me to get a new one. I told her no and she asked why. So I told her that its not worth the risk to me of either one of us getting charged with identity theft (although I'm not 100% sure how identity theft charges work, I just know that its not good if you have someone else's ID).

She went on about how that never happens and I'll be fine. I told her no, I'm not doing that. And she said "whatever. I'll find some other way then". I just said "okay" and we haven't talked since (this was yesterday). 

I'm just wondering if I'm being to prude-ish about this? Is it really that big of a deal? I don't want her to feel like she's missing out on stuff. Any advice is much appreciated. Thank you!
<bot>: Sister asked to buy my ID off me so she can go out drinking, I said no. She is now upset with me.
