here's the story...

Preface: My sister’s been having hip problems 
(problems with her hip not problems being “hip”)

Mom: How’s your hip?

Sam: *limp, limp* Painful, I just came home from the physiotherapist

Mom: Did he diagnose you?

Sam: Not yet, but there’s a lot of inflammation. 

Mom: I think I know your problem

Sam: Really?!

Mom: Ya, um what’s it called…?

*pause*

Dyslexia.

Sam: What?!!?!

Mom: That’s why your hip hurts!

Tracey: Her hip pain is caused by a learning disorder?!

Mom: Tracey! Don’t be rude!
