It is exactly 2:30 PM on a bright Saturday in London. The Southbank area is incredibly crowded today. If you look towards the River Thames, you can see that several large tourist boats are sailing slowly under the bridges. Near the famous London Eye, a group of street performers is dancing to hip-hop music while a huge circle of people is watching them and clapping.

Right now, my friend Mark is not skating; he is sitting on a concrete wall and is eating a large slice of pizza. Behind him, two professional photographers are taking high-quality pictures of the skyline. A young girl is running after her dog because it is barking at a pigeon.

The weather is perfect, so many people are not wearing coats. Instead, they are wearing sunglasses and light t-shirts. I am standing near the skatepark, and I am recording a video of a boy who is performing a difficult trick on his skateboard. Everyone is having a fantastic time!
