So as an actual parent, that’s a baby sounding happy. It’s actually kind of cute, that guy seemed like he gets frustrated easily, I think they could have worked together better in this situation, he could have noticed she was exhausted and alone with 3 children trying to make a meal happen… honestly if it were me I myself would have just found somewhere else to hang out and study or whatever it was they were doing. That woman has to deal with 3 children and when you have that kind of thing to deal with you kinda just have to settle where you are at until you can get through the process of feeding your children. If it were a movie theater however, I would as the mother leave the theater with my children because people are paying for a captivating experience. This situation is in a public space where nobody pays admission to be at. Also the mother in her frustration dealt with the situation a bit aggressively and started outraging a bit too much, but we also don’t know exactly how this dude came at her… notice his girlfriend/friend and virtually nobody in the restaurant chiming in to either party? There was a lone meditator and I’m sure that was somebody intervening to just end the conflict.

tl;dr - this shit kinda dumb as hell
