Post offices or emailing
In the age of Internet everything had changed. Post offices are no longer necessary and the Internet is more useful than they.
One positive aspect of the Internet is cheapness. Emailing saves paper and petrol. Also people should not buy evelopes and postage stamps.
Furthemore, Internet is accessible for everyone. People have access to the Internet any time and any place.
In addition to this, emailling saves a lot of time. Messages arrives immediatelly and they can not be lost.
Howewer, post offices are still important, because not all of people have got computers or the access to the Internet.
Also, if people buy something from websites, somebody has to deliver them.
Another advantage of post offices is that they offer non-postal services like money orders or banking services.
To summarise, post offices are still popular, but more and more people prefer emailling.
In my opinion, post offices belong to the past, not for the present, but their importance is still tangible.
