We all know in our previous days we used the post office to send the mail to our friends and relatives but right now the email really helpful for that but what do you think which is more useful and which will be more safer?
The cheapest domestic letters cost more than one dollars take between one and two weeks to arrive here where I live, so sending a letter are not something I would use. E-mails or other social media are a much better way to communicate with friends and relatives.
