Answer:
Why, is not this better now than groaning for love? Now art thou sociable. Now art thou Romeo. Now art thou what thou art—by art as well as by nature, for this driveling love is like a great natural that runs lolling up and down to hide his bauble in a hole.
Step-by-step explanation:
Mercutio is insisting that love made Romeo different. He was not the same anymore. He is not being sociable. Mercution saw him as a kid who could think of nothing but the idea of playing with a girl's genitals.
