she wasn't terrible to lily in high school? but she found her perky cheerleader thing so annoying and was super jealous of the time she spend with everrett so she was kind of dry and sarcastic and lily just didn't get her dislike. to be honest (and if this doesn't work definitely just let me know!) i can kind of see her start hanging out with him more to hang around a bit more? because otherwise, she just sort of stepped back and spent her time getting into trouble somewhere else. maybe there were a lot of double dates and things? otherwise, hazel was definitely that girl that showed up to parties with alcohol and cigarettes and obviously didn't have anyone at home keeping tabs on her or trying to instill a curfew. she probably "snuck out" all the time to see him.
