Who would have thought that in a mere 10 years or so e-mail would have pretty much taken the place of letters. I remember as a child writing thank you notes for gifts received, now you just pick up a phone or send an e-note.
Back when the boys were in boot, we had to write in order to correspond. They did not have access to telephones or computers. But as soon as they were out, it was back to e-mailing. And we still stay in contact that way as well as via our cell phones.
Yet, I would never have believed it if someone told me that I would have an e-mail account, even 10 or 15 years ago. And look, I have three. I wonder what the next 10 years will bring :)
