Option 1, change the dormitory, (not recommended)

The disadvantage is that the success rate is not high, others will have a lot of ideas about you, counselors will think you are not tolerant enough, and you don't know what your future roommate will be like. Enjoy it yourself.

Option 2, Cold War, (risky)

Disadvantages: She may continue to harass you and make you feel worse behind your back. After a long time, she will automatically ignore you. )

Option three, be nice to her, buy some snacks to share with you, and try to show affinity. If she bothers you, you can hide out so that he can't find you. Don't complain. If he speaks ill of you, you can pretend to be wronged and pathetic in front of everyone, so that everyone thinks it's her fault (recommended, but bold but thick-skinned).

Advantages and disadvantages kill her. She is annoying and pretentious, but everyone looks peaceful and psychologically tolerant.

Option 4, divert attention (recommended)

The advantage is that you can participate in more activities, make more friends, or enroll in various classes, so that you won't meet him often, and you can expand your circle of friends yourself, provided that you don't let her integrate into your new circle.
