need advice asap 🥲

guys pls help me out 😭 my cousin sis and her daughter came over and that girl keeps telling everyone she wants to use my laptop 🥲

i honestly don’t like sharing my things… ik it sounds selfish but it has my important files and folders and i don’t have any backup rn, so i’m scared she might mess something up

how do i refuse her politely without sounding rude 😭
