I eat meals very slow and don't swallow much air, but I still burp afterwards. That's another reason why I am sometimes reluctant to go out to restaurants for meals with family, I always feel a big burp coming after I finish my meal, and try to push it down by swallowing hard, because I don't like to do it loud at the dinner table. Well, it's not
loud loud, but people can still hear if they're sitting next to me. I hate people hearing me burp.
If I hold it in it usually comes up later when we've gone home, but then it tastes worst when you've held it in longer.
I hold it in when we're at restaurants but my parents criticize me for it at home but they have no problems passing gas while we eat. When I call them on their hypocrisy they tell me that they are trying to teach me social skills for when I go out.
