At least she managed to bow.
"Morn" is a normal morning greeting in Sweden as well.
It's almost as if she's letting her boobs speak for her.
Not really. Just pointing out differences in how people socialise.
A goal appropriate for her would be to hold a conversation, or to at least greet everyone back who greets her.
Fairly normal with a guy being more persistent than girls. Guy are more used to having to work to interact with girls.
If she doesn't like being alone, she's more of a social anxiety case than an introvert.
"I returned a greeting properly!"
Well, there are flaws with it, but she did return it. Also, she's absolutely right to celebrate every step forward.
