We know she's still stuck in the mindset of being at primary school, so I wouldn't be shocked if she hates July because it's been engrained in her as the month schools break up for six week's holiday.Yikes...her face looks tired and she just looks incredibly ill.
Her month ranking system, whatever you wanna call it is so annoying. She does something like that every year. Whenever a new month or season comes around she always has to tell everyone that "ITs hEr VeRy FavOurITE SeAsON/MoNth". It's so annoying.
"Oh such torment that fate has brought me! The blinding sun only reminds me of the summer prison I have been cast into - like a scorching desert, barren of education and bereft of house points. Lucky I have my teachers' phone numbers memorised! They may have me permanently diverted to voicemail, but the sound of their voice messages will be like an oasis in these academically arid summer weeks." She probably had a countdown calendar to the first day of school like it were Christmas.
Regular adults usually just gauge the months by when birthdays, Halloween and Christmas falls. January sucks because it's dark, cold, and there's the post-Christmas blues, paying off Christmas bills and going back to work (if you were lucky enough to get time off) - Ruby will obviously have no concept of things like bills and work. And otherwise all the seasonal months blend together.
She's an utter clown.
