Bonnies mind is more child-like

agree with twilightalice

Mer!!, Boonie sometimes reminds me a mad person XD

I love Bonnie but hands down. Meredith is much more mature.

omg ofcourse meredith!!

It's not to diss Bonnie because i love her but Meredith is by far more mature than Bonnie. Bonnie can be a tad on the whiny brat side a little like a kid who's older sister (Elena in this case) is the favorite child so your gonna be self pitiful and whiny secretly, sorry but it's the truth. But on the show Bonnie is so much different and she really is way more mature than anyone else on the show

Duh! Lol. I adore Bonnie but she's childish :]

Obviously. Can't believe people voted for Bonnie.

agree with twighlightalice

Of course, without a doubt...

well duh i mean shes all come in a situation and then bonnie (in the book) is like OMG WTF ARE WE GONNA DO RUN RUN RUN!!!!!

Bonnie's smart she just doesnt show it but Meredith is more mature...:)

in the book they are both idiots that do everything elena tells them to. They are more like her servants than her friends

I hate elena in the book! she is shallow and selfish

Bonnie it's not mature at all!
