I also use Skype a lot to stay in touch with my family in Michigan. We moved in 1993 ten hours away. 600 long miles. When we moved we could send letters in the actual mail. Oh how I looked forward to getting letters on fancy stationary with stickers decorating the envelope from my grammie. (Heck I still look forward to getting the occasional letter from her.) We also could call them occasionally. But you know you could never talk too long because it was a long distance call.
My sons will never know what a long distance call is. Heck for the record, there will never be a time when my boys aren't able to immediately receive a phone call no matter what they were thanks to cell phones. I remember using pay phones. I can't remember the last time I saw a pay phone to be honest.
