Sometimes I have a tough time getting along with myself. When I was a child, I needed a lot of attention... and I don't have a small ego. For me, appearing on a stage or presenting a cake is the same thing. You need a crowd around you to do it.
Nothing has existence unless you, I, or some living creature perceives it, and how it is perceived further influences that reality. Even time itself is not exempted from biocentrism.
