Farting is normal, as long as it is done when you are alone. This isn't a pleasant experience to share. If you are in the toilet, then fine ,,, who cares! But intentionally farting around, is plain rude. The burping are annoying. Its rude as well to do it in public. If you can't hold it in, turn your head to the side, cover your mouth and try to do it as quietly as you can, then 'excuse me'.
