Glass envelop

In this modern age,we have many way to communicate with each other:
Phone call.
Text message.
Emailing
Or chat on the internet.
We like new things,we enjoy new technology.New technology is nice and convenient,it make life easy.For example,I am writing this blog on my Blackberry and I decided to public it through my mobile in a few minutes.It's fantastic,right? But how about a text writing,I mean write a  letter in your own handwriting and travel it by post office.
Last year,I received a letter from British,it's a special letter because it's put into a bottle---with a glass envelop,this letter from a man who named Leo and he is my age,he traveled across the Chanel and put a paper with his name and address into a bottle and then threw it into the sea.now this glass envelop in my hand, I never dreamed of receiving a letter from a stranger through this way,it's a nice surprise.
Now,we are good friend.we write to each other by email and sometimes chat on internet by Skype.Yesterday he told me he'll drive his mini car travel across Europe,when he arrive a new country he will send me a card.Thanks Leo. I also invite him to my country.Up to now,we never see each other,we didn't know what does others look like.
