Becoming a superhuman

As you stay hidden, you bump into something and it falls over. Your brother is shocked for a second and he carefully inspects what the heck that was before you uncloak and you fall over. Your brother laughs and helps you up. You nervously tell him and he accepts. You don't really feel as if you should become a hero, but you use your powers irresponsibly and overall for playing around. As you prank people and toy around with things, you end up becoming quite the annoying person. You end up in normal life at an office job. While still going for pranks at every turn.
