I’m in New Hampshire with my family for a long weekend. My aunt and mother just showed me an email on my aunt’s iPhone. It says, “No Subject,” and “Sender Unknown.” The date sent is 12/31/69. “Isn’t that weird?” my mother exclaimed. We went to look at it again and it is, of course, gone. Now we’re all wracking our brains trying to figure out what the hell happened on New Year’s Eve, 1969, and why someone is waving at us from all the way back there and then just to say hi.
