Goof

Erin is right handed, Julia in real life is left handed.

When she's looking through the classifieds and circling ads or making notes, she uses her right hand, as the real Erin would.

But near the beginning when she's standing in her kitchen eating a can of fruit, she's holding the fork in her LEFT hand, which Julia would be doing real life.

Shame that she goes to the trouble of writing with her RIGHT hand like Erin, but in that one scene she does her natural Julia left-handedness.
