Alice and Jasper just so happened to not hear the phone conversation between Bella and her "mom". (Maybe James just has a very womanly voice?)
Jacob is so hot with his shirt off!
No humans noticed the confrontation at the wedding. That would have TOTALLY ruined appearances if that happened.
Because Lauren wasn't exactly friendly to Bella, she just so happened to be scammed and have all her hair cut off.
The hottest boys around just so happened to not even be fully human.
Bella, one of the klutziest and weakest people ever, just so happened to be the coolest vampire.
