Sachys: What kind of stuff did yer dad do?
He was a part time commercial artist, an engineer, but also a full time accountant to pay the bills for the family.
I always felt kind of bad that when I got contracts with his parent company, that they treated me better than they ever did him. His division wasn't bad to him, he just didn't really get any of the wining/dining/travel opportunities that they gave me, and I was an outsider. Hell, without talking to him and understanding what the company needed/faced, I couldn't have developed the system view that I had.
Totally different area and level from division to corporate, but his knowledge of the bigger picture invariably aided me, and allowed me to feel confident in seeking them out as a potential client.
