In the scene where Eric comes to the restaurant where Eric works and she stops playing (her violin) and gives it to a customer, and she & Eric leave the restaurant without picking up the violin and you see them going into his house sans violin.
Eric drops the Christmas tree off his car into the snow which covers half the tree. When Eric and April bring the tree into Eric's house, there isn't a bit of snow on the tree.
In the beginning as April decorates her lawn, she breaks one of the large candy canes. You can see her trying to put it back together.
