What Are The Essential Items I Should Bring For A Camping Trip?

Hey everyone, I am thinking about bringing my girlfriend for a camping trip. I thought that will be a fun thing to do and it can help to spice up our relationship. But to tell you the truth, I have never been to a camping trip before. Therefore, I don't really know what to expect. Most importantly, I don't even know what I should bring for the trip. Can anyone tell me what are the essential items that I should bring for my camping trip? Any answer will be appreciated. Of course, it will be better if you have been to a camping trip before. You can certainly share your experience with me. Thanks in advance.
