How should I interpret ぼくたち また なかよしさ！? I was trying to read a book for children, the title is ぼくたち また なかよしさ！ I guess it says something like "We also are good friends!" or "We are still good friends!" or "We are good friends again!" but I'm not sure about any of them. How should I see that sentence to get to a better interpretation?
