During an art show we organised in our flat in London, I invited the audience to lie next to me in my bed. I was interested in how I would interact differently with different people that would share my small bed with me. The experience, both the audience's and mine ranged from very awkward to very pleasant, depending on chemistry, level of familiarity, and the number of people being there simultaneously.
I shared my bed with 89 people that night.
The first person who lied with me played me a song on his iPod, and when it finished he told me "The song is called I Wish I Knew You".
