I just happen to check about cultural things and chance upon this page
To Andeee, You are AN ABsolute Dirthy and smelly IDIOT!!! People burping quietly is consider good and polite. So what if there is food smell. It is natural and human. You are not human at all. TOo bad you sit to the person next to you. BUT BUT, they did not do it on purpose. IT is their needs. It is not a filthy habit or acts. Got it???!!! You are stupid and retarded iF you hold it in. If you do not like it, you can F back to your cave and don't come out and that's how God created us. Air sure goes in when we eat, drink and even swallow our own saliva. So we need to burp often. You should stop swallowing , stop eating and drinking. Spit out your saliva and die in hell. oh ya.. you are seriously mentally ill to think like that. F to mental hospital and lock yourself inside ya. RETARDED BASTARD!!!
