I feel like I got the gist of this translation, but started second-guessing myself partway through. There are also a couple areas where I want some advice.

ぐふぐふ：I translated it as laughing, but would another word be better? Maybe giggling?

あ　お　屋外で？！：I'm not sure whether Intern-chan was trying to say a different word at first, or if it was just an あ of surprise. To be safe, I went with "O-outside?!" even though it doesn't include the あ at the beginning. Any suggestions?

Also, does anything else look iffy? I felt confident when I started translating this, but now that I'm done, I'm second-guessing myself on most of it.

Someone thinks someone is talking about something else...
