阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

The Nigerian postal service has witnessed a reduction in the number of letters sent, especially by individuals, due to the alternatives of email and text.

“People prefer these over letters, because of the speed, although letters serve many purposes, other than conveying of messages", said Barry Varley Tipton, principal of Cherry Field College.

But some people think that the vanishing(逐渐消失的) art of letter writing has grave (严重的) consequences for students, teachers, the economy, society and the beauty of reading from loved ones, because letters in those days usually had a variety of styles .

A lover of letters writing, Hajiya Aisha refers to the occasions she has seen people enraged, because their connections at a cyber cafe took 56 seconds rather than the usual 36 hours. She says, “Although letters are slow, waiting for something good is not wholly a bad thing. Nothing beats a hand written letter.”

"When I was a graduate studying overseas twenty five years ago, my mother wrote to me daily. It was wonderful to receive those letters. They often said nothing more than everyone was thinking of me. I continue this tradition with several friends who are scattered worldwide. Hand written letters show the love that we have for family and friends. Email cannot replace the smile of actually getting the letter. The warm, sincere thank- you note, or the sweetly scented love letter we usually received and sent in those days is irreplaceable" she said.

Will electronic age stamps replace letters? Hopefully not, since it takes with it a culture rich in colour, history, and communication. Letters, like bits of ourselves, deserve to be stored away for future readers, giving them insight into details as small as the price and pattern of stamps, and as great as personal insights exchanged long ago.
