in need of an answer. please read the bottom portion!💕

So A few weeks ago my oldest sister invited my youngest sister and I over to spend a night with her. we were all in her room talking the next morning and my youngest sister took a seat on her bed with us and her box spring on the bottom cracked/broke. A bed should be able to hold 3 people and 2 babies right?? Well now that her bed has broken she keeps asking me to replace her box spring.... even though our little sister broke it... but she obviously cant afford anything right now because she's currently in college and the money she does make goes on her books and whatever else she needs.....if this happened to you would you make your company pay for you another box spring or would you just buy it yourself?
