the standard of being close to one’s co-workers

(1)I heard something shocking from my senior a few days ago
(2)I’m close to someone in the company
(3)- I think we’re all close enough, but what do you mean
(4)Let’s meet outside and play
(5)Then we’re not close
(6)Who’s going to meet someone from the office outside? It was such a shock that I almost jumped through the roof
