Haha, neither did Carol! Well, except Maria (which was her only close female friendship before Nat). Now she's close to Nat, but doesn't really understand women in general. So clearly Carol and Irene need to be friends. Duh.
You're doing great!!! Don't get her started, though. She will go into a long explanation about multi-dimensional theory and space/time conundrums. I can't stop her.
Oh, Harley is legit crazy. It's fun! I don't know whether she actually hears voices or not, but she enjoys letting other people THINK she does.
