I'll reserve this spot for now, will add the main content later

I'll reserve this spot for now, will add the main content later. I just typed this sentence on my screen and stared at it for about ten seconds. The cursor blinked behind it, on and on, as if urging me. But I wasn't going to write the main content, because the main content hadn't arrived yet. I opened the fridge and took a look, then closed it. I walked back to the computer, and the cursor was still blinking. I pushed my chair back, stood up, and went to get some water, this time for real. I placed the water bottle on the desk and took a sip; it was lukewarm. Then I sat down and looked at the sentence 'I'll reserve this spot for now,' feeling like it had been reserving the spot for a long time, and the main content still hadn't appeared. I opened a new tab, then closed it. I opened a folder and saw a file named 'Untitled,' clicked on it, and it was empty. I closed it and opened another one, which was also empty. I thought, 'Whatever, I'll just type something.' I typed a line, deleted it. Typed another line, deleted it again. Later, I wrote 'I don't know what to write today,' felt it was too honest, and deleted it. A car drove by outside, making a loud noise; I waited for it to pass. After it quieted down, I typed 'I am sitting here now,' felt it was okay, and kept it. I also kept 'The cursor is still blinking.' Then I realized I had already started writing the main content, even though this wasn't the main content, and I didn't know what to call it. Anyway, the spot is reserved, and I've typed some words, so this should be fine. I took another sip of water; it was still lukewarm.
