Literally the same thing happened at my high school like 8 years ago when I was a freshman, the cops went and confiscated the guy's computer and psp, and found a bunch of granny porn on both. Lulz were had.
Worst wrong text thing that happened to me: I was texting my ex before I went to bed to try to convince her I wasn't interested in this other girl emily (don't know why I gave any fucks...), and sent her a text that said "Goodnight, Emily, sweet dreams, can't wait to see you tomorrow!" Psychotic Ex-girlfriend shitstorm ensued.
