What would you do in your last 48 hours on Earth?

Let’s say that something horrible is going to happen to Earth(hit by an asteroid,melt down etc)and you and other picked humans must leave Earth and go to set a colony on another planet to assure that humans won’t disappear.You have only 48 hours before the launch.What will you do in this last hours on Earth,before leaving Earth forever?You can take your family with you(wife,kids,brothers).So besides that what will you do?
Note:The world works in a normal way because the people who will remain don’t know about the disaster that going to come.
