I haven't gotten caught doing too many bad things, wow.. Some of it would really suck lol.
I have two memories that always stick out and they were both when I was in about 8th grade.
I got caught burning my report card from school by my mother. I didn't do anything the whole term, out of 7 classes I had 6 F's.. So when the card came in the mail, I immediately got a hold of it. Too bad for me my Mother knew the card was coming in that day, so when she caught me she just called the school to get my grades anyway..
The other thing that comes to mind was really f'd up.. I had just gotten a faster internet connection, Mom was at work so you know I want to go check out some porn right? Well, she came home a bit early and as I was shutting down the PC, it froze on a picture of this girl.. Well, lets just say it's not something my Mother was happy about seeing when she walked in the door..
