Despite her grumpy demeanor, Joanne was a fairly good teacher when it came to cars. It wasn't difficult to her either, but she supposed she just had a knack for this stuff better then other things. She felt him close behind her and turned her head to grin at him a little before going back to showing him how to fix and change things. She was getting dirty though, and greasy, but that didn't stop her. She just reached her hands further into the engine to fix whatever needed fixing. "That's.. the basics," she said after she was done. "Everything else requires taking out parts and either changing them or fixing them. Or getting under the car."
