<human>: This morning, my roommate accidentally knocked my atomic clock off of our wall and it hit the ground hard. The glass broke (there was already a crack in it though), and even after we found the battery and put it back in, it stopped working.  

I'm not really all that upset. She did apologize, but she didn't offer to replace it or anything... should I ask her to? I've had this clock for a very, very long time, and not having an analog clock on my wall to refer to will be a bit unnerving.  

Reasons why maybe she shouldn't have to replace it?  
* It was knocked down by accident (I know for sure, I saw it happen)  
* It already had a long crack in the glass  
* It was hung somewhat precariously  
* It doesn't have much sentimental value  

Reasons why she should, I guess?  
* It was my clock which we both (I think, I know I did for sure) frequently used to check the time  
* I can't afford to buy myself a new clock right now

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I feel somewhat ambivalent but I'd really like to have a working clock. Would it be shitty/selfish of me to ask her to replace it?
