The two exercises I chose were the third and fifth.
For the third exercise I had to listen attentively for five minutes in a public space, I chose a local park, and write down the first eight things I could hear from the environment. It is an unusual feeling to pay so much attention to every noise I can hear as I often wear headphones or I am talking to someone, therefore paying less attention to my surroundings. Certain sounds stood out to me and once I had tuned into them it was hard to lose focus on one sound.
