Some people don’t feel very welcome, accepted or loved in one Church, so they pack up and leave to another Church (in search of love and warmth). Some say they’ve not been able to fit into the ‘cliques’ that exist in their local Church. Others are uncomfortable with a new Church leadership style (usually following a change in Church government).  For some, the Pastor and/or Church members are not ‘nice’ or caring enough (or at all). I heard it been said once, that a couple walked away from a Church because an usher was rude to them.
