My older brother is trying to ground me? WTF?

My mom and dad are on vacation this month to Europe, leaving my older brother (19) and I(16) home alone. Of course, they left him in charge. Why? I don’t know. Anyways, last night, my brother went out to dinner with some of his friends… so I decided that I would go over to my bf’s house for an hour or two. Well, we watched a few movies, and I didn’t mean to, but I fell asleep in his bed with him, but we didn’t do anything. JUST sleeping together. Nothing sexual or hard core. My brother got home and didn’t know where I was because I didn’t tell him. I know he wouldn’t have let me go to my bfs house if I had asked him, because he doesn’t like him. It was 12 in the morning, and we woke up to my brother banging on the window (embarrassing). The car ride back to our house consisted of him yelling at me. And today, when I got home from school, I told him I was going to a friends house, then he told me he was grounding me until our parents get home.

Is he allowed to do that?

I mean… its not like I had sex or got drunk, or did drugs or anything… and I’m still alive.

Isn’t he way over reacting? What should I do?
