Winter Break?

For the past week or so I have been on break, I have a little less than one week left. I few days ago I went to a party which is something I do not normally do, but I had made a promise to go so I sort of cornered myself. I had planned on only stopping in, having a few pictures taken as proof that I was in fact there and then heading home. I don't really know what happened but all of a sudden it was almost 1 am when I looked at the clock! What the dickens happened?! I ran to my phone to see 12 missed calls- holy shit, I am a dead man. A man rush to get home ensued and I was able to sneak in without my mother noticing but it was a close call in the morning. When I woke the next day I went upstairs to see my mother and she was not happy to say the least. She asked what time I got home and I may have fibbed and told her I was home at 12 and I did not tell her because I did not want to wake her. It took a little persuasion but I was able to convince her of my innocence.
I guess my question is, how do parents not wonder about their children when they know they are going out?
I must be a nun or something because I would be so scared of my parents every time I went out.
