 Hello, and welcome to Writing with Technology. This video will help you know when to use these four different kinds of technology. What if you were waiting for someone? It looks like this person wants someone to pick her up, but her friend is not there. What should she do? Should she send a letter through the postal service? No, that would take two or three days, and she would be there a long time. Should she send an email? Well, she doesn't have a computer. You need a computer to send an email. Should she get on Facebook? She doesn't have a computer, so again, Facebook will not work. Should she send a text message? Yes, she does have a cell phone. She can text her friend to find out where her friend is. She can find out where her friend is right now. What if someone wanted to apply for a job, and the job said online applications? Should that application be sent through the postal service? Through Gmail? Through Facebook? Or through a text message? Through Gmail? Very good. Never, ever use text to apply for a job. And don't send a letter in the mail if they asked for email. What if you just wanted to send a message to a coworker or to your boss? You don't want to send a post-it note. This picture is just being silly. You want to send a message through the computer that will show up on your coworker's computer. You will send an email. Email is an excellent way to document and make sure that your friend got your message. What if you just wanted to wish happy birthday to one of your friends? Not a big deal, just a little birthday wish to a friend. You could send a card through the postal service, or you might send an email or even a text. But Facebook is a fantastic and very popular way to send a birthday wish to a friend. What if your husband or your friend went grocery shopping, but you just discovered that you need milk? How would you tell him right now that you need milk? While you are at the grocery store, please remember to pick up milk. Text messaging is the best way to let someone know something that you need to have happen right now. What about legal documents? These are all very important papers that must be kept forever. If you need to send a document like this to somebody, a text message will not work, and neither would Facebook. Sometimes legal documents are being done through email, but the postal service is still the best choice for legal documents. What about this? Your family just got brand new puppies. Isn't that sweet? Are you going to send a card to all your friends in the mail? Are you going to send out Gmail or text messages? You'll probably post something on Facebook. Facebook is a great way to let people know what is going on in your life and to share your news. But if you are getting married, however, if you are getting married, you need to send out wedding invitations. Announcing your wedding on Facebook is still not quite socially acceptable. You will want to use the United States Postal Service with real professional printed invitations. I hope you enjoyed learning about the Postal Service, email, Facebook, and texting.
