When romeo enters how does he show that his depressed mood has changed

Romeo makes it clear that his depressed mood has changed by finally engaging in the exchange of puns with Mercutio. The two of them go back and forth with their jokes, until Mercutio says "Why, is not this better now than groaning for love? now art thou sociable, now art thou Romeo." He is pointing out that Romeo is finally being himself again, which is far better than how depressed he had been about love. 

Encoding

Explanation:

Memory Encoding is the crucial first step to creating a new memory. It allows the perceived item of interest to be converted into a construct that can be stored within the brain, and then recalled later from short-term or long-term memory.
