Why, all the things you mention cover with precision and completeness the lessons the nascent Church was to learn:
Either you haven’t been to one or have chosen to forget what one is like. They were laying around drinking and eating and debating what their places of authority were going to be in the promised kingdom. They had no idea about eating the body or drinking the blood of Jesus. It was a gathering like all the rest and the back and forth was what you would expect in a fraternity party. It was a testing of “machismo”; a “oneupmanship”. I imagine Jesus’ slapping His forehead in wonder that these were the people the Father had entrusted His church to. He was probably happy that the Holy Spirit was coming and would get the blame for the potential trouble they would get into. An hour later He, in frustration, had to dismiss them in the face of trial with “go back to sleep”. I remember doing that with my sons, trying to get them up to rake the yard.
Even at His ascension they were still lusting after their places in the kingdom wondering when it was coming so they could start preparing for the furnishings of their castles. They had to be told over and over again to quit wasting time fishing for fish and start fishing for men. This is no different than what Paul experienced at Corinth, although that was more like a co-ed fraternity/sorority party. There he told them to grow up.
