Since the prompt revolves around the character's friend moving away, a few concepts you could consider are:
- Brooke is in denial about her friend moving and makes some attempt to stop her despite not being able to
- Kayla begins packing and the reality of the situation fully hits her
- Brooke fears that she'll lose contact with Kayla once she moves away, or vice-versa
- Kayla is afraid she won't be able to adjust to her new surroundings or make new friends
