popping gum!, popping gum!

I mean I've experience each one of those but the one I would remember best would be a family member. I mean it was my younger brother, we were sitting around watching t.v. and he was just sitting there chewing and popping his gum over and over again. I thought at first maybe he'll stop and realize how annoying that is, but then as it continue to happen over and over again. I got a little upset and try not to raise my voice but I remember still coming off a little mean and told him to stop popping is gum seeing as it was distracting me and watching my television show. But I should have known better younger siblings are usually rebellious against anything you tell them not to do, so of course shortly after he stopped he began it again. And I had to get up and yell at him (which I felt bad afterwards of course) and told him to either stop or go spit it out. So he finally stopped. Crazy.
