Think back to the last time you sent a letter in the mail. Not e-mail. I have been for a long time too)
It is possible to send a letter by e-mail now, there is practically no need for paper messages. Therefore, the received letter, written by hand, will cause a lot of emotions.
?Kids learned how to fill in the index correctly, write the recipient’s address, glue stamps and send letters to their friends. And at the post office they told us how to send parcels?
By the way, we have friends in other countries with whom we correspond by regular mail and send gifts to each other. Do you have such friends?
