My first guess is he hasn't taken the time to cultivate the skills to manage his family and possibly his co workers either...

He's probably been faking it up until now and getting away with it... most engineers do...

There ARE skills to work with people that you can cultivate, and a mountain of Don'ts that engineers DO all the time... He lilkey has'tn tapped into any of that.

WHen I iwas growng up I wouldn't listen or participate in anything unless it made logical sense to me... I needed the family stuff explained to be logically or i wasn't going to opt for it...

YOur H likley saw three people seeing your daughter off already so he figured it wasn't necessary for everyone to be tehre... a good engineer is very economical with time... They won't send five men to do something if four is enough...

I would need to know more about his work to offer more detailed examples... But I think you get the idea...
