She said

SeYoung (the sister I'm doing Bible Study with) came to Friday Service for the first time today.

After service, as we were walking home, she said, "I regretted coming the first 3 minutes I was sitting in service. There was so little people and it seemed so serious and boring."

Then she said, "But... it was fun."

This is (nearly) exactly how our conversation went:

SeYoung: 재밌었어 (It was fun)

Me: 진짜요? 재밌었어요? (Really? It was fun?)

SeYoung: 응, 재밌었어. 재밌었어... 재밌었어. (Yes, it was fun. It was fun... it was fun)

SeYoung: 이런 어처쿠니없는일이. (How absurd/ridiculous)

[...]

SeYoung: 이런 재밌는걸 여태까지 너네 혼자했답말이야?! (You guys enjoyed this by yourselves all along?!)

It was absurd/ridiculous to her that she wasn't out with her friends on "Friday night," but that she was at church worshipping God. It was even more ridiculous that worship could be "fun" and "enjoyable." 

AHHHHH YEEEEEEEAA :) She finally got a taste of how FUN it is to be praising and worshipping God.

(She doesn't seem to know that this is only the beginning.. hehe)

Excited to see how God will continue to mold and shape this sister :)
