I was actually just thinking this with the wedding log, but it's so great when we have shenanigans that allow for character mingling like that. It really shows how the game can come together ;o;b and it's great because it's not relying on events or things like that but rather the characters themselves.
So more things like that should happen. ... Idk about Tomoyo's shrine, but stuff like the school dance were also awesome for character mingling like that.
