FML

Last night I had a sleepover with some friends. 2 girls and 3 boys. When I came home everything seemed normal. My twin sister had a couple friends over, and we hung out for a while. Then as I was sitting at the computer, my friend's mom ( the friend I slept over with) told me that my dad had just called, asking about the boys that slept over! HOW DID HE KNOW!?!?!?!?! Now I'm grounded till FOREVER and my dad's disapointed in me. FML
