It’s true that it’s not something we feel comfortable doing, but I think you’re going pretty over the top with this one :D
We wouldn’t fight anyone for invading our private space. Nor would we really tell them to fuck off. We would simply sulk in uncomfortable silence through the trip and very awkwardly and apologetically ask the person to move their shit when it’s our stop.
Later we would warmly think about the deep and personal friendship we made along the way.
I don’t really get it why people jump through these major hoops just to get Windows working the way they want it to. Just ditch the problem.
