You and I must have had the same father!I never knew my grandfathers, but my dad loved gadgets almost as much as I do. I'm pretty sure he'd say something along the lines of "Well, at least he's not out buying drugs."
Mine was a pretty good dad, all things considered. A whole bunch of us are taking this question a bit too seriously!
My dad was born just before the Depression. His whole life was hard until after the War.
He NEVER begrudged ANYONE their indulgences. EVER. But we never had two extra pennies to rub together growing up. I'm dead serious. My dad made sure we never missed a meal, but they weren't always extravagant, lol.
He'd UNDOUBTEDLY think that me having more than one razor and some canned foam was just a waste of time and money.
He used a cart as soon as they came along, but he never got past the whole "wet head is dead" thing. As a matter of fact, he was mad one time when he sprayed hairspray on his underarms thinking it was deodorant! Lol, think of the times those regular working stiffs lived through, the changes they saw in their lifetime.
My dad used a horse to plow as a boy. Saw Space Shuttles launch and land.
I doubt he'd bother to get his pants in a bunch about how WE shave.
