  Due to the standard electroweak model we have become accustomed to think
about a neutrino $\nu$ and its antineutrino $\bar \nu$ as distinct particles.
However, it has long been recognized that the apparent distinction between them
may be only an illusion. Implying these words of Prof. B. Kayser we give an
alternative insight in the physics of neutral particles (neutrino and photon).
The proposed formalism which is based on the Majorana ideas could also be
useful for deeper understanding of the nature of electron.
