How did Via’s dad cheer her up?

Via's dad cheered her up by poking fun at her and making her laugh.

But she didn't come back that night. Dad did. He told me Auggie had had a bad first day and Mom was helping him through it. He asked me how my day had gone and I told him fine. He said he didn't believe me for a second, and I told
him Miranda and Ella were acting like jerks. (I didn't mention how I took the subway home by myself, though.) He said nothing tests friendships like high school, and then proceeded to poke fun at the fact that I was reading War and
Peace. Not real fun, of course, since I'd heard him brag to people that he had a "fifteen-year-old who is reading Tolstoy." But he liked to rib me about where I was in the book, in a war part or in a peace part, and if there was anything in there about Napoleon's days as a hip-hop dancer. It was silly stuff, but Dad always managed to make everyone laugh. And sometimes that's all you need to feel better.
