The invasion of personal space still wasn't working for the princess. She tried to deal with it the best way that she could, but it still made her uncomfortable. Not because she minded Samuel touching her as much as he minded the odd feelings she felt when he did so.
At work it was also worse for her because she didn't want to give away the effect that he had on her when there were people that could take notice of it that she would prefer not to. She didn't have a problem with public displays of affections. She had a problem with risking others using it against her at some point in time.
She wasn't sure if Samuel didn't care about it or really understand how much that bothered her as this was the second time that he had done something like this. Once was before he knew but now that he did, she had expected him to better understand that she would prefer to avoid such situations.
