If I have friends or relatives who live far away, I prefer to communicate with them or by email.
Firstly,it is very convenient to communicate with people through Internet by email.
Secondly,communite through email is very fast.If we want to write letters,we should wait for a long time before it has been sent to our friends or relatives since they live far away.
Thirdly,we can save time and efforts by using email.We don't need to write all the things in one letter.It never mind whether our frineds or relatives are at home or out of home when we send email to them.
In a word,I'd perfer to communicate with my friends or relatives by email,it's very convenient and fast.
