Answer:
The truth is Farting is natural for every person and animal. The body needs to let the gas go. It has been proved tho that girls/women fart three times more than guys and this is because their bodies produce 3 times more gas, it has also been proved that girls/women's farts stink alot worse than mens to and this is because of a higher level of sulfur gases in their farts than us men. The truth is you souldn't stop anyone from farting weather its a man, women, girl or boy its a natural bodily function and the gas should be realised as soon as they get it. Holding farts in damages your insides. However i don't know the girl you are talking about but if shes going up to people and farting in their faces kind of thing you can say to her that if she needs to fart she is most welcome to but out of politeness for others please leave the room to do it. Hope this helps
