Grand daughter lives 3 hrs away and works. Mom thinks she is coming every nite and spending the nite. Some nites she says she is there and in the bed asleep when we all know she is not. Some nites mom sits up waiting on her. No one can convince her that she is not coming. Granddaughter has tried telling her she has to work and cant drive 3 hrs to work every day. Mom still thinks shes coming and will wait up for her all nite. HELP!
