Life's A Gas

Why does it still make me feel uncomfortable to fart while using public transportation? It doesn't have any bad effects on human health like smoking that they had to legally stop even in the stops. Is it then because I don't like to play around with it, instead just let it go, and then it comes out loud. But then they talk so much and also quite loud on the trams, trains, buses and it usually doesn't make more sense than that sound coming from another hole.
Also they push a button recently on the tram I have to take to tell us stories of events from half a century ago which some folks decided a few years ago were revolutionary. I don't agree with them as those back then doing these 'revolutionary' things wanted to kill my Grandfather and his whole family, because he literally believed in communism so he helped everyone in that goddamn little village, even when his eleven kids needed food and clothes just the same. And then those people he helped the best he could turned him on the hands of these 'revolutionary' men. But the 'evil' Sowiet soldiers appeared just in time, so amongst others my Mom didn't have to die because of human greed, lies and so on.
But then again, why on sweet fucking earth do I have to listen to such revolting lies and also pay for taking the public transport. I didn't ask for being treated with lies there, I can listen to them on the news if I please.
Finally the noise made by most of these trains going under- and over ground would cover any noise I can make. Most of all their noise, in best case scenario, would mean we're making progress, and getting to our destination, unlike in some cases as it happened lately when the noise meant fire or other unplanned events along the line. Should they pay me for the chance of such events at all?
Back to why I'm not just taking it easy, and do whatever I feel like doing. Now it might be up to having been brought up in a way that in times passed seemed and worked as the right one, but now it's all useless and make people suffer only. Exactly like when they try to hold it back.
