  Doubly special relativity considers a deformation of the special relativistic
kinematics parametrized by a high-energy scale, in such a way that it preserves
a relativity principle. When this deformation is assumed to be applied to any
interaction between particles one faces some inconsistencies. In order to avoid
them, we propose a new perspective where the deformation affects only the
interactions between elementary particles. A consequence of this proposal is
that the deformation cannot modify the special relativistic energy-momentum
relation of a particle.
