In the poem "Free," the two lines that suggest the speaker finds joy and beauty in their way of life are:
a) "A bed is limiting, the night is my playground."
c) "I’m the lucky one, my roof is the sky."
These lines convey a sense of freedom and happiness with the speaker's lifestyle. The first line expresses a playful attitude towards the night, while the second line reveals a perspective of feeling fortunate with a non-traditional living situation.
