Kumon. Oh mah lawd, Kumon.
They start you off with little kid problems (assuming you're just. That. Stupid.), and eat away at your life slowly as you sit there in your house on Saturday afternoons, scribbling away at your Kumon packets while everybody else maintains a social life. To the Kumon instructors, everybody learns the same way. Can't solve math problems that quickly, but understand the basics of it to be able to work it out carefully? Sorry, Charlie. Let's do it again until your brain works in the manufactured Kumon way.
To the people who are not yet enrolled in Kumon: when your parent makes any reference to the place in any way, shape, or form, RUN LIKE THE WIND.
Friend: So, Cassidy... what did you do this weekend? I didn't see you all last week; where were you?
Cassidy: Oh, you know... sitting in my house, doing Kumon packets.
