LOL... I am indeed married with the usual 2.4 children etc.... I don't know if 'understanding' is the right word, more 'acceptance'
Mrs <tuffty/> gets to do what she wants to do and the the <tuffty/> juniors get a look in too... all is good...
I have spent less time on the car more recently as there is less to do but I have been messing with cars since I could drive so she knows what she was letting herself in for... mostly!! LOL
