How do I extend my STV visa in Thailand based on personal experiences?

Just wanted to say thank you for the help I got in this group a while ago. Special thanks to Tod Daniels and Benjamin Hays.

I am from Norway. Got my STV visa in November.

Yesterday I went to Saraburi immigration to extend.

Had copy of my passport (page with pic). Copy of page with entry stamp and Tm6.

Copy of "blue book". Actually I didn't bring, so my girlfriend had to call owner house. Send it by phone and we print out 😅.

Then had to fill out a couple of forms. One I think name Tm7. The other one was something about rules for overstay. Just had to read and sign.

The officer complaint little bit. "Mr Roger, you not fill in everything. You not understand English naa"😅.

I just smiled and said sorry, I speak not good English. Speak Norwegian. I am trying to learn Thai. She smile and say ok. No problem.

Have a happy weekend guys. Thanks again 🥰. Roger.

By the way, my flight to Norway is on May 5 so I am good 👍
