Could you differ?

When you were learning how to ride a bicycle, you'll ask a person to place a good grip on your bike, so that you won't fall.

The first time you were learning how to walk, you'd like someone to watch your back, so when you're about to fall, that someone will catch you, will leave you no harm, you're safe and sound.

Now that you've grown up, things changed a bit. You'll walk, yes, this time without anyone get a hold on you or to catch you when you fall. But in this path you're walking, you'll eventually find a person, a certain person, who will help you to stand once again everytime you fall.
