You're such a selfish girl

Let's do the logical thinking here. Let's see what would you do in such case.

There are 4 persons (3 boys and 1 girl) sharing a electric oven since 3 years ago. After they had moved to different floors in Hostel, the girl brought up the oven to her own room which is at 8th floor. while other 3 boys who say stay in same unit at 6th floor got to climb up to 8th floor to use the oven.

There is one time, one of the share holder decided to brought down the oven to their unit in 6th floor, because there are 3 out of 4 persons there, by logical thinking the oven shall be put at there. Okay, the oven was in 6th floor, but just for 2 days, then the selfish girl brought the oven to her own room again.

Do you think this girl is selfish? Or boys should give more priority to girl? How do you think?
