Is this normal??????

When I'm at school and with friends I'm a totally diffrent person than when I'm home. When I'm at home Im a rolorblading, ice skating, knife thrower, tennis player and I also onley listen the Kelly clarkson songs but when I'm at school I'm a cheerleader, popular, have lots of friends ( witch I hate most of them even though they think there my bestfriends) and listen to all the new songs is this weirdd??
