  This note compares the usual (absolute) Gromov-Witten invariants of a
symplectic manifold with the invariants that count the curves relative to a
(symplectic) divisor D. We give explicit examples where these invariants differ
even though it seems at first that they should agree, for example when counting
genus zero curves in a class \be such that \be\cdot D=0. The main tool is the
decomposition formula in the form developed by A. Li--Ruan.
