There is nothing wrong with any of that. However, when is the last time you sent a real letter or received one in the mail? I love opening the mailbox and seeing mail from a friend. Even if it is only a few lines on a card, it means they took the time to think of me, write me and mail it to me.
When I was in college and when we first moved away from home, Moma wrote me faithfully at least once a week. My kids call me a packrat or a hoarder but I sure am glad I saved some of those letters that Moma wrote. Moma has been gone for almost 6 years and it feels so good to be able to go back and read the words she wrote, where she told me she loved me and more. They are a treasure to me.
Emails and texts are nice but you might never know what a card or letter would do for someone. Take that few minutes while you are waiting at the Dr or something and ask God who you can be a blessing to and write that card or letter. You might just open your mailbox one day and get a card or letter back from them also. It might just make your day so get out those cards and paper and pen and start writing.
