1) The narrator is turning 11 years old but doesn't feel 11, rather she still feels 10 and encompasses all her past ages from 1 to 11 inside of her. 2) In class, the teacher wrongly accuses her of owning an ugly, old sweater that was left in the lost and found which causes the narrator great embarrassment and shame on her 11th birthday. 3) Humiliated in front of her classmates, the narrator breaks down crying uncontrollably, wishing to be invisible or much older rather than having to experience the humiliation of being 11 years old.
