Where in the story does Charlie meet people with difficult personal issues like cheating, abortion, and drug use?

Abortion:

February 15, 1992

That’s when she told me she was pregnant.

I would tell you about the rest of the night, but I honestly don’t remember much about it. It’s all a very sad daze. I do know that her boyfriend said it wasn’t his baby, but my sister knew that it was. And I do know that he broke up with her right there at the dance. My sister hasn’t told anybody else about it because she doesn’t want it to get around. The only people who know are me, her, and him. I’m not allowed to tell anyone we know. Not anyone. Not ever.

I told my sister that after a while, she probably couldn’t hide it, but she said she wouldn’t let it go that far. Since she was eighteen, she didn’t need Mom or Dad’s permission. All she needed was someone to be with her next Saturday at the clinic. And that person was me.
