I'm not lazy, I was just making my Lazy Linda:
1) As a child, she was in an accident (in which her mother died) after which she developed derealization and depersonalization (a defense mechanism of the brain), as well as problems with the functioning of the brain and breathing, which is why she sleeps poorly and is constantly tired.
2) He photographs everything with a film camera given to him by his father, in order to capture reality and himself in it.
3)She is friends with Henry, at first simply because they were deskmates, and then his chaos and noisiness helped her stay in reality(and they also have a huge difference in height, and this is also taking into account that Linda is constantly hunchbacked).
4)Draws cats out of boredom.
P.S: I ship her with Bert because I think they are just adorable!
They have the vibe of these cute silly romantic photos, they are not afraid to seem different to each other, I see a blissful silence between them, when they do not need words to say how much they value each other (yes, I am sure they both do not particularly like to talk so much that at their Buddhist wedding, in the future you will understand why it is Buddhist, they will simply nod in agreement).
P.S.S: Linda is one of my favorite characters in the show, she deserves more content, I didn't make up an age joke so as a fact she is also 14.
