Your Bicycle always has time for you. Bicycles don't complain and don't ride away from you when the road gets rough. Bicycles don't shave. Bicycles don't snore. Bicycles don't leave a mess in the kitchen or bathroom.
Bicycles are better protection in a bad neighborhood.
You can try out as many bikes as you like before you get your own. You don't have to feed your bicycle. Bicycles never argue, you are always right. Bicycles never wake you up in the middle of the night, for any reason. Bicycles never try to show you off to their friends.
