Fun fact: Sakura had absolutely no idea what Fugaku Uchiha looked like. She knew what Mikoto Uchiha looked like, but for some reason (probably that she didn't concern herself with Uchiha affairs when she could help it) she'd never encountered Fugaku before. It was ultimately a matter of necessity that the girl in the pink braid ended up taking the unoccupied portion of the bench. The tea shop had become unbearably cramped by the time she passed it by, and the rain was beginning to get so heavy that it was in danger of compromising the wax seal coating the large scroll she carried.

Although it slowed her down, it was better to wait for the rain to pass than to fail to deliver important documents in a state that would actually be usable because she continued through the rain when there was shelter she could have used.

She recognized his features as both Uchiha and old, but the idea of sitting next to an unpleasant man was more favorable than the loud and rowdy people who were the only other places she could try to sit and wait for the storm to pass with.

She was careful to sit on the far end so that there was a respectful distance between she and the Uchiha already occupying it, but otherwise she didn't bother to ask permission. Asking permission opened up the possibility of sitting elsewhere or standing, and she wished to do neither.

She did glance at the kittens in his lap and basket briefly when she sat, carefully arranging the scroll so that it wouldn't crease or crumple under its own weight over however long it would take for the rain to pass...but she did at least make no attempt at conversation.

That would probably have been awkward.
