Best way to "sneak out"?

So I'm basically living with strict parents and they let me go out and all, they just need to know where and with who. I've been talking to this guy for awhile, and I wanna know have you guys ever lied to your parents for hanging out with a boy? And what was the lie? I'm looking forward to seeing him cause we live in different cities, and I don't even drive, but he does so he could pick me up anytime...
