Singapore – Personal Space
An interesting thing to watch in an overcrowded city is how people create spaces for themselves. The trains here are especially interesting because it’s not uncommon to have only centimeters between you and others. If by some miracle you’ve got a seat, it could be centimeters between you and the crotch of someone standing in front of you. Books used to provide a barrier, but no-one reads books anymore. Now phones have taken over that function. By avoiding eye contact and plugging in to some music you can effectively block the world and claim a private space.
