Today people have many ways to communicate. Such as internet, telephone and write letter,etc.
The development of technologe makes people can choose the way they like to communicate.
But many years ago people can only wait for letter.
But face so many ways to commnicate I would perefer to make phone call. I can hear your voice and touch your feeling and knowing what you said immediately.
Write letter is still a good way to exprise my feelings except to have to wait several days. Through email is the very common way for us today and it is faster than waiting for letter's come.
So it is the best way to communicate by email. I like it very much.
