I was out grocery shopping with my daughters yesterday and we were using their car.  So when we went to load the groceries into the trunk, there wasn’t enough room.  Why?  Because they had stashed their presents for other people (like me and their Mom) in the trunk so we wouldn’t see it.  This isn’t a good idea.  Take the stuff out of the car.

Similarly, don’t leave stuff in the back seat either.  It’s just a magnet for thieves.
