I'm upset that my sister was not helping me when I needed to use the printer at 2 AM. She said it was because the family was sleeping.
What made you need help with the printer?
It's really hard to print at 2am so she ruined my printing.
I am sorry that your printing got ruined but it is not good to be angry at her, she did try to help you even though you guys were printing too late. You could have woken up the rest of the family.
The print was really important and now it is too late and I can't print it anymore.
I understand it may have been really important, but I don't see why you need that that 2 in the morning. You should really be considerate of your family when they're sleeping and to not wake them up.
