There would be no truth whatsoever in her words if Idun were to say that she disliked the unexpected company of utter strangers. She loved strangers. She loved the unexpected. Pairing those things together made her happy in a way that was difficult to explain. She was clearly an enthusiastic person, a very social creature by nature. It didn't even matter who or what she was socializing with. Idun honestly could've been happy in that tree with that bird for the rest of the day. Birds were fascinating little conversationalists, after all. Idun liked to think she could understand certain birds, particularly the ones who perched on her finger and sang sweet little bird songs. Those were the ones with the stories, the ones that belonged here while Idun also listened to the stories of the trees.
Birds were not her only interest. She loved conversations with actual words, and a god willing to talk to her was a god she was normally eager to talk to. Idun was indiscriminately affectionate, since there were no warnings of Stranger Danger when she was growing up, and she hugged and kissed like she was reuniting with a dear old friend always, no matter who it was she was greeting. Idun should've been a goddess of friendship. If there was a way to adopt an extra patronage or two, she would, just so her amiable attitude would not surprise a single living soul.
But her application for an additional patronage would have been denied if it were reviewed in that moment, right after her bird flew away and a god appeared without any warning, on her tree branch, in a completely rude, uncalled-for fashion. Talking and presumably attempting to flatter her. Ohh, flattery would get him nowhere. Idun was immune to his flattery. The tree had been so peaceful, and her bird had been so chipper and gentle. And all that was ruined.
Bragi was no unexpected stranger she expected to enjoy any time soon. Idun decided to let him remain a stranger as well. Just to spite him for ruining her enjoyment of nature. "It was a good tree," she said with a huff. Idun was not a rude goddess, not usually, not without an impossibly good reason. She didn't actually have a good reason, and she realized that as she cautioned a curious glance his way. This softened her expression a great deal, but she was still determined to look a little grumpy. Just because. "Hello Bragi," she said, taking his hand. He had nice hands. Not that she cared. Idun just happened to notice. "The tree over there is nice too. I climbed it just yesterday."
