Roscoe Button Timeline and Summary

Roscoe is born to Benjamin and Hildegarde.
Like his mother, Roscoe resents Benjamin’s reverse aging and demands that he stop it.
When Roscoe’s age surpasses his father’s apparent age, he demands that Benjamin call him "Uncle" around the house. Roscoe refuses to take Benjamin to prep school and sign him up.
Roscoe even asks that Benjamin wear fake whiskers and glasses to look older.
