But here, she doesn't, comfortable enough to understand the silence isn't an awkward one, that he simply doesn't have anything to say at the moment. Rachel lets it go, content to walk at his side, her hands still around his arm. They go a couple blocks before she speaks again.

"Thank you. This is nice, it was a good idea."
