Hm.

I was trying to think of the best way to explain my new JTE situation. So here goes:

Tsuji-sensei was a horse.
Notani-sensei is a camel.

Both get you from point A to point B.

However when one switches from horse to camel, one thinks, "This is difficult only because I know what it's like to ride smoothly."

Poorly explained, but there you have it.

And if you've ever ridden a camel... well you just know what it's like.
