a)
The protagonist's life goals are that of lounging, relaxation, and watching television. All of the
people coming in and out of the scene will have varying relationships with the protagonist, and thus different interaction with the character himself. They're goals will also vary (friends wanting to borrow money, his girlfriend coming to pick a fight with him, friends wanting to eat his food, etc.)
b)The obstacles the protagonist has to overcome, is the constant violation of the guest/host relationship by his peers. There aren't many obstacles for the other characters and extras, just going into and out of the apartment.
c)The protagonist will overcome the objective of having rude friends through his unwavering patience, and oblivious nature throughout the story. The characters shuffling in and out of the setting, will have to interact with the protagonist however that particular character should act, given their relationship to the protagonist. And whether they're hungry, thirsty, angry, sad, happy, tired, high, etc., will determine how they behave in a living room with they're best friend.
d) The protagonist will do nothing, but flip channels, maybe appear to speak one or two words, but for the most part, just kind of sit there, zoned out in front of the tv. The characters will talk to, insult, compliment, thanks, apologize, and beg for the food/beer/hospitality of the protagonist, and will either succeed or fail.
e) The extra characters will either leave or continue to press they're luck with the protagonist, some will give up quickly, others will not. The protagonist will just keep on in the same manner as before.
f) The actors are engaged in drinking beer, smoking, shouting, moving all over the couches at times, yelling at the protagonist or another extra, yelling at the television, running around, horse-playing, etc.
