Best ways to sneak out?

Ok. Just to start off, DON'T sneak around. You will get caught if you continue. This is from personal experience, so trust my word. I love my boyfriend and we never have any serious problems with each other but my family had issues with him (very stupid issues). So, after a while we realized my parents weren't letting me go anywhere with him. This made me upset. So for a few weeks every wednesday (cuz I didn't have any classes) he would come over my house and we would hang out and stuff. My mom caught us. She didn't see him, but she felt that I was acting suspicious and found his sneakers in the basement. Sneaking around for a parent is like a stab in the back. This seems unfair but if you become a parent you will understand. I'm 18 by the way. If you are caught somehow that you are not home, it will look bad if you're with your boyfriend. Just ask whoever you need the permission from to see him when you want to. Not being able to see my boyfriend any more kills me and gets me really depressed because so many problems arose from sneaking around. I wish we could still see each other, I would have waited months if I could still be allowed to see him..
