Rocks

I was walking to work, and it was almost lunch time. I thought I'd eat first, and then go to the office. So I sat down at an eatery with 3 other people (friends?), and we ordered. While we were waiting for our food, I suddenly realized that while I had my backpack for work, I didn't have my laptop. My friends said that perhaps I had already dropped it off at work, and so I decided to first go to the office to check. I stood up and walked towards the office, which apparently was located in the building next door. I started walking, but my backpack was so heavy that it weighed me down. I tried to keep walking, but I hardly made any progress. Finally I took off my backpack, and dragged it along on the floor. The backpack was so heavy, almost as if it contained rocks.

Finally, somehow, I arrived at my desk. Someone had left me a note - a message had been etched into the wooden surface of my desk. The person claimed that she was my younger cousin, but I was confused because I didn't have a younger cousin. In her note she said that she had come by to say hi and to see if everything was okay. Meanwhile, a few of my coworkers (who were actually my coworkers in real life) walked past my desk and carried on with their day as usual. I opened my backpack, and my laptop had been with me all along...
