Honestly, I found it hard to understand myself.
It was like they were having two different conversations at the same time but I think the boy with glasses wanted to ask why he reacted how he did when the blonde boy saw him with the older woman and he explained that his parents told him to be wary of strange adults who are with children and that if it turned out that she wanted to do strange things with the boy with glasses he would attack him as he can't hit a lady.
Also, I think glasses was hurt because it would seem like he would do the kissing bet with anyone.
Sorry if this is hard to understand. I do not remember names
Finally caught up.
