Facebook: I accidently clicked on close button on a friend in the chat bar! How can I bring him back on chat?

There is "x"(close button) beside the name of every friend in chat bar in facebook. I accidently clicked that button beside a friend's name and he got deleted from my chat! How can I bring him back?

On the bottom right hand side of the facebook window, there is a tab that says Chat with a number in parenthesis. You click on that and find their name and click that. That will restore the chat box. You can also go to their profile, and in the words under the profile picture, you can find Chat with (person).
