oh, i'm not really an expert on that time (too young to have experienced it, all i have is secondhand impressions haha) but from what i hear about that time your comic feels true to it. sorry if i gave the impression i was more experienced with it than i am ^^".
anyway, it's really cute that the gag was inspired by your real life, i love that. the best fictional stories are inspired by real situations sometimes. i do agree it fits too, it was so real for them haha. you make them feel so real, honestly.
