MERCUTIO: 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 drivelling love is like a great natural,
that runs lolling up and down to hide his bauble in a hole.
In this lines, Mercutio is attempting to say that Romeo shows his true self when he is joking with his friends and he wants to highlight that Romeo is better off than when he is groaning for love because when being in love, he acts like an idiot.
