Totally annoyed

My shift shifted an hour ago, and I felt annoyed with a colleague already. She will be on vacation for 3 weeks starting next week and I will be doing her job. Everyday, we get paperwork that we prepare for the next day, since she'll be gone after today. When the paperwork got printed to day, I was planning to deal with it. SHE WOULDN'T LET ME!!! I'm like, I'll be doing your job next week, I want to deal with the papers. She says, she's working today and it's still her job to do it. My thing is, because she won't be working next week, I don't want her to mark my sheets the way that she likes. We all have our own ways to deal with the paperwork. But she totally insisted on doing them. Now, I'm just very annoyed and angry. I plan to white-out everything after she has left from her shift. I like my paperwork to be neat and tidy, not have unnecessary markings on them.

Sorry, just had to vent to someone, somewhere.
