Prompt: …it was heavier than I expected…
I went to the shops one day and when I got there I saw a small bag of big colourful marbles on the shelf. I ran over and I picked it up and it was heavier than I expected. When I went to the counter, it cost $5.50. Luckily, I had the same amount in my card, in my wallet, in my pocket. I went back home and I looked at the marbles and they were really good. I played with them with my brother and I hit his marble and I got to keep it.
