Private chat to clan leader

Everyone has a private events that u don't want to tell other members in the clan chat.
We should have an private chat direct to the clan leader to tell the reason.
For example, when you cann't perticipate the clan war, and leader asks you on the clan chat why. But it is a private thing so u don't want the other people knowing it.

They can't say the words "real life issues" or "its personal"? Those exact words should be more than enough. No clan member/clan leader needs to know more than that.
