i did something bad to my sis

so like i was so jealous of how my older sister always gets all the attention. she’s always telling mom and dad about her big accomplishments and stuff, but i just feel left out. one day i got this idea to mess with her diary... yeah i read it, and then i switched a few pages around. i wanted to see if she’d notice and freak out. but now that i did it, like i’m actually kinda scared of the consequences. mom found out anyway and grounded me for a week. why do i always end up doing these dumb things? im such an idiot sometimes.
