I feel DD m, as one of 6, found all were similar to her but they enjoyed different things and maintained friends in other flats and from their courses. Clubbing was a thing then but just in year 1! Clubbing is dying. Loads have closed. Parties are way cheaper. Lots of flats have no party space.
DD in y4 had dinner parties as the flat actually had a dining table in a large lounge/diner. Priorities change. Often in y2 DC maybe haven’t been discerning with friends because they’ve known them for 5 minutes. This gets sorted by y3!
