First, I must bring lunch box, and snacks to eat there!
I think snacks and picnic are deeply intertwined!
As I said gimbap, and crackers are the best!
And I want to bring camera someday!
It will take a picture, and also good memories!

"May people know that you, whose name is Jehovah, You alone are the Most High over all the earth." - Psalm 83:18

= 

First, I must bring a lunchbox and snacks to eat there!
I think snacks and picnics are deeply intertwined!
As I said, Gimbap and crackers are the best!
And I want to bring a camera someday!
It will take a picture and also make good memories!
= When a sentence starts with a phrase like these:

• As I said,
• However,
• In fact,
• For example,
• First,

it's natural to put a comma afterward.

= With only two nouns, don't use a comma.
= Great job!
