Typo errors

Typo errors are a common thing when it comes to chatting. Some errors are funny and some typo errors can land you in trouble. Let me state an incident that happened in my life while chatting with a very old friend of mine. I accidentally typed "who are you" instead of "how are you". That typo error was funny because he knows me well and I know him well. But, imagine typing the same thing to your client or someone while addressing them formally. So, be sure to check what you've typed before sending it over to the other person.
