A good cover up story? ?

Okay so tomorrow night I want to hangout with this guy, were just friends. But he gets off work at 10:30 pm so we would hang out probably around 11-1 or 2 ish. I'm almost 18!!! And my parents won't really let me be out that late (because of my past) I need a lie to get out of the house for a couple hours. The greatest lie I could think of was: "i was going to watch a midnight movie premier at the theater" but since I work there and we close at midnight. If my parents passed by there just to check it out, no cars would be there?! So maybe I can say in going to see it in IMAX theater in the city (they won't go there) haha HELP!! it's innocent fun! I just want to see him before he moves/:
