She thought to herself, why is George so childish? Did he think that by doing more things, he wouldn't have to worry about the other mistakes he made before? Aria wasn't exactly touched by George's care, but rather was still bothered by the way he handled things.
He could treat her coldly, just because of what others said. If something more serious ever happened in the future, would George not know what to do? She thought that if he was treating her coldly now, then perhaps he would just ignore her completely then?
Aria wasn't afraid of these things, and didn't feel there was anything about George ignoring her. Only that Aria thought this way of handling things was extremely unhealthy. Communication was essential for long-term relationships.
However, Aria was left speechless by George's meticulous handling of things. It seemed there was no way to directly get angry with him. Instead, she decided to take a shower first, and when she was ready, she would talk to George.
