  With simple estimates based on recent observational data and the assumption
that among known FRB sources most repeaters with extremely high rates of
repetition (super-repeaters) are already identified, we demonstrate that the
hypothesis that super-repeaters and one-off events come from the same
population of magnetars is not self-contradictory. In this toy model, the
super-repeater stage has a duration of about a few years and the period when
one-off events are mostly emitted corresponds to the active life of a magnetar
$\sim $few$\times 10^3$~years. Intervals between strong events (observed as
one-off FRBs) from the same source are $\sim10$~years, corresponding to the
expected time interval between giant flares.
