Barty was at the ministry of magic with his father. Apparently, he wanted to show him how he worked and what his future job would be. He wasn't happy at all. He hated this. Not because it was a bad job, but because it was the thing that got his father so distant from him. He rolled his eyes most of the time and didn't really listen to anything that his father was saying. This place was just full of old people acting like God. He didn't want to be one of those.
