Sometimes a drag

Tomorrow I'm going to need to find a way to go get my prescription. My parents don't know I'm on it and my car is in the shop at the moment, so I need to come up with a decent reason to borrow a car. When I want to go somewhere, especially in one of their cars, my parents aren't big on the answer to the question "Where are you going?" being "Out." Being home can be a drag sometimes-- I want to show respect for my parents, their rules, their feelings, but a lot of the time doing that makes me feel like a teenager.
