A: I’ve been planning to go skiing with my best friend, but she is good at it and I’ve never done it before.

B: Don’t worry, when you first start skiing they’ll help you go down the bunny hill to get your feet wet and you won’t have to go down a giant slope.

Note: This idiom means to “begin doing a new job, activity, etc., usually in a slow and simple way in order to become more familiar with it.” The expression originated in the 16th century. We know a frightened swimmer hesitates to get into the water and slowly tries to get the feet wet in order to get used to and test the water and then can dive in easily once ready. Similarly, when faced with a new situation, people want to take small steps to get used to it.
