You and Carl were best friends since you were little before the Apocalypse, your father died defending Rick so he took care of you from the beginning you had long/medium hair which started to bother you when you started to grow, then when you got to Alexandria and settled there you decided to cut your hair but Carl always liked your hair that way because he loved touching it while you talked or were idle, so when Carl saw you with scissors about to cut your hair he said

"Hey, what are you doing?!"
