Context: I forgot how much I enjoyed it . It 's very much a pick - up game ; we 're playing on a basketball court , and not even a full court -- it 's about the size of a half court , with cracked concrete , not grass , and when it rains ( and it 's San Jose during the rainy season ; inevitably , it always rains ) , it gets really slick in places , not that it 's exactly nice to play on before it starts to rain . But it 's fun .
