There’s probably a whole ‘people you share your commute with’ thread in there somewhere.
I have Manspreading Rupert Murdoch, Papa and Child, and also Muttley, who has a constant, really loud, unhealthy sounding laugh exactly like Muttley from Wacky Races. When she gets on the carriage there’s a kind of audible groan then shuffling as everyone immediately puts their headphones on to drown it out.
