The Topic of Belching

Ally was talking to April one day and she was complaining about a random encounter she had. What she was talking about that day was the fact that someone just randomly burped in her face while in line somewhere. No warning, no apology, just unmitigated guttural rage aimed straight at her face, to which April laughed a little. The conversation went on for a while, and at one point, April had the fortune of having a belch sneak up on her right as her sentence ended. Ally giggled at this, but what April said nearly made Ally fall over. April was saying that what happened to Ally was just rude, "but when I burp, it's punctuation."
