My dad doesn't trust me on the computer?

My computer used to be upstairs, but my mom had it moved downstairs because my dad kept complaining that I would be tempted to look at porn, but I caught the hypocrite looking at porn himself, he ended up turning it off when he saw me and I pretended I didn't see. He's currently sleeping right behind me which he never does when I'm already upstairs asleep. Why is he acting like this? It annoys the crap out of me.
