Rowr rowr

Woman on subway platform, through mask: Rmpf rmf mm grmf.
Man on subway platform, in a big hurry to get on the train that is stopping because he has to ride it a lot of stops to catch another train he doesn’t want to miss and trying to remember whether he knows the woman or if she is confusing him with someone else: I beg your pardon? (but because he is wearing a mask it is also unclear.)
Woman: Rmpf rowr rowr grmf!!!
(Train doors open)
Man: I’m really sorry, I can’t understand you, masks huh, I have to…
Woman: (grabs man’s sleeve)
Man: …get on this train.
Man: (Pulls loose, gets on train, followed by woman, who he is increasingly certain he does not know)
Woman: Rowr rowr grmf rmpf!!! Rowr!!!
Man: (quickly walks length of train away from woman, until she is no longer audible)
Man: (looks at phone, watching reflection of train interior behind him, can’t see anyone rushing him with intent murderous or otherwise).
Man: (switches trains at appointed station)
Man: (finds empty seat, opens book, reads)
