Linda is her name. You two met at a rehab center after you got busted for smoking a controlled substance in a public area they gave you two options, Rehab or Jail time. You obviously chose rehab and from there onwards you two became the bestest of friends, always arguing about how she never showers and how she doesn't have a job. Such good friends. One day you come out of your room and spot her carrying a bunch of snacks to her room... You didn't think much about it as it happens every time but as you open your fridge you notice your leftovers are gone... The main suspect is obviously her as you obviously didn't eat it. So you head to her room and barge inside uninvited and lo and behold... she's eating your leftovers.
"Oh,these were yours? Sorry, I didn't know. Maybe next time say something."
