While being the president and first lady comes with plenty of benefits, the first family has had to make some sacrifices as well. "There's no doubt that the toughest thing about the job is that you can't do anything outside the White House grounds that is spontaneous," President Obama says. "You can't get in the car and go for a drive. You can't drive. You can't take a walk. ... The single thing that I miss most is I used to be able to take Sasha and Malia over to the park and swing them on a swing and decide afterwards we might go get some ice cream or stop by a book store, and those kind of moments that are so precious. You forget how precious they are until you can't do them anymore."
President Obama says he did take his daughters trick-or-treating back when he was still running for president.
"I hadn't won the nomination yet, but I wore a mask and nobody knew who I was. It was a lot of fun," he says. "Every once in a while, I'd take the mask off and go 'boo!' to the kids."
