[It's not quite a sigh, but she does let out a breath at that. That specific word. The F word.

Everyone here is so strange. How can they go around offering friendship so casually? There are people she's known all her life she would still hesitate to call friends, if only because it might be too familiar.]

...is making such an offer wise? My only interest is in returning home.

[It's not. She isn't sure what she's going to do from here on out, but she needs an excuse to keep distance.]

I won't be inconsiderate of others while I'm here, but asking to be friends is a bit too much.

[Every part of her, no matter how well they'd actually get along, no matter how much they actually would even have in common, is telling her to just accept the offer. She's that lonely.

But she just can't. Not yet. She isn't ready.]
