Retsuko's personal dilemma of living through monotonous days is, once again, incredibly relatable. I'm a bit of a nihilist, myself - I don't think there's anything wrong with lazing your life away as long as you don't hurt or inconvenience other people. Personally, I prefer having a high degree of repetitiveness in my daily life - it helps me keep control and prevents nasty surprises. I don't have any big life goals I'm working towards, either, and I'm quite content living the way I do.
But then, there's always that nagging feeling of having to justify this attitude of mine when society at large seems to be caught up in a YOLO trip (like every time my mothers asks me why I don't want to take more than one vacation trip per year). I don't object to an anime series promoting a more varied and adventurous lifestyle, though. It makes for more interesting stories, anyways.
It appears that Retsuko's mom knew how to hit all the right notes to get the girl to try out the whole speed-dating deal. The event itself was pretty funny, too. The fraudulent tiger had me completely fooled, too.
