You don't have to deal with priests or blood-tests to register your Motorcycle. You don't have to convince your Motorcycle that you're a motorcyclist and that you think that Motorcycles are equals. If you say bad things to your Motorcycles, you don't have to apoligize before you can ride it again. You can ride a Motorcycle as long as you want and it won't get sore. Your parents don't remain in touch with your old Motorcycle after you dump it.
Motorcycles always feel like going for a ride.
Motorcycles don't insult you if you are a bad rider. Your Motorcycle never wants a night out alone with the other Motorcycles. Motorcycles don't care if you are late. You don't have to take a shower before riding your Motorcycle. It's always ok to use tie downs on your Motorcycle.
