See? I’m an old-fashioned romantic man. I wouldn’t call you. I wouldn’t text you. I wouldn’t e-mail you either. Instead, I would write ‘I love you” with invisible ink on white paper, fold the paper, put it into an envelope, and seal it. I would write your name and address on the envelope, place a stamp, walk some blocks to the nearby mailbox, and drop it there. Upon receiving the envelope, you will know I sent it to you, but I wonder, will you open it?
