  We present the results of multi-epoch global VLBI observations of the Compact
Symmetric Object (CSO) 0108+388 at 5 GHz. Analysis of data spread over 12 years
shows strong evidence for an increase in the separation of the outer components
at a rate of $0.197\pm0.026 h^{-1}c$. Given an overall size of 22.2 $h^{-1}$pc
this implies a kinematic age of only $367\pm48$ yrs. This result strongly
supports the idea that radio emission in Compact Symmetric Objects arises from
recently activated radio sources. The presence of weak radio emission on
kpc-scales in 0108+388 suggests recurrent activity in this source, and that we
are observing it just as a new period of activity is beginning.
