Peek a boo.

"A ghastly grin wrinkled his face as he gazed at me" (121). This is some odd imagery. When Victor is trying to make the lady friend for the monster, the monster pays him a little visit to see how things are going. He is happy as described in the quote, but the imagery shows the emotion of Victor. He cannot stand to look at him. This imagery creates an image of a creeper looking in a window. He doesn't seem like a little kid that is getting something he wants (which he is like). He seems like this crazy guy who is spying on Victor. This imagery shows how why Victor reacts as he does. He cannot stand the idea of creating another thing that is so scary to look at. The description depicts him how all of humanity sees him. No one can see past his scary exterior. This is what causes all of the problem in the story. Humans are superficial. The monster learns that the hard way.
