It was free and I didn't took it

On 9th of June, a Saturday we went to Amsterdam to play tourist. I am Asian so everyone is greeting me in English. The capital of The Netherlands is nice and I never took canal boat trip so we decided to just go and do it. I was very fortunate that it wasn't really warm and enjoyed the one hour trip. At the end we could decide to take the earbuds with us. These are in-ear buds which I don't use and find very uncomfortable. It's also the reason this post isn't accompanied with a picture.

One I forgot to take a picture on the boat and two taking a picture of something that I didn't bring back with me. Of course I understand the fair includes the earphone but when I don't use it, what is the reason to take it with me.
