Regarding his appearance, and style of bike, I didn’t pay close enough attention to notice. Now that said, if he were dressed as a 1920s paperboy, I probably would have noticed. So I guess the takeaway from my limited observation would only be that he didn’t look radically unusual. And to miss Lynne’s suggestion, again I didn’t pay him close enough attention to recall specifically what else he said. (My wife would attest to the character flaw that is my limited attention span. ) However, for whatever it may worth I do recall that he said he, “and his parents”, had been away. The inclusion of his parents being the only additional detail here.
