[No one from no where]

My boyfriend and his friend were high and sitting on the couch when this happened:

S: Hey, bro?
R: Yeah bro?
S: Do you gotta pee?
R: No. man.
A few moments pass.
S: Hey, bro.
R: Yeah bro?
S: Do you gotta pee?
R: No bro.
S: Hey bro. I gotta pee.

And then he finally got off the couch to pee.
