I was watching BD2 last night and…

I was wondering why did Bella pick and choose when to wear the brown colored contacts?

When Charlie came to see her at the Cullen house, the contacts are understandable because she’s trying to still play “human”.

When she dropped off Renaissance at Charlie’s house to go see J. Jenks, she ***was not*** wearing the contacts.

But then at dinner with J. Jenks, she’s wearing the contacts. *He doesn’t know her, so why wear them?* On the way home, no contacts.

But what I’m really confused at is her wearing the contacts at Christmas… when everyone in the room had seen her without them at that point (and are aware that stranger things have happened 😉)?

Is this a continuity error, or am I missing details from the book (which I read over 20 years ago)?
