@bold đ I think that's just the character...army people are more "stiff" because they need proper posture and do all that marching and stuff. But he's also stiff by his logic and rules because of army discipline. They are exaggerating the army life in this show. My grandpa was in the army and my dad's also an army kid and they aren't that uptight...my dad is very organized and punctual but that's just his personality...I don't think it's because of his family's army background
That's what I meant for stiff the overall thing...not just the posture...I know many folks worked and still work...but they don't show those traits...but that's OK....those are minor touch up I guess for the show...we can bear that as long as they don't make the whole thing boring......
