Emails are great. They are instant, you can share links to websites and pictures. However, no matter how many smiley faces you put in them, they are pretty impersonal. Now, a letter has much more character. There's something about opening the mailbox and finding a note from a family member or friend. Seeing their handwriting is like seeing their personality. It takes effort and time, which makes you feel special that they spent that time on you. You can keep them forever, tied together with a pretty ribbon. Emails are deleted without a second thought.
I often wish that we still wrote letters like they did in the 19th century. They didn't use envelopes as often as they simply folded their letter into a cute little square sealed with wax. It would be great to have my own seal for my letters. They're so mysterious and charming. The recipient would know who the letter was from without even looking at the end of the letter. If you had to share secret information, you wouldn't even have to sign your name. Like the Scarlet Pimpernel! You could save English aristocrats from Madame la Guillotine during the French Revolution with the help of seal! You can still find wax and seals today at crafts stores and lots on different online vendors. I expect a resurgence of letter writing in the near future.
