When I was 21 and got my own apartment, I literally did not know how to work the vacuum cleaner. Why? Because I grew up spoiled and pampered and no one showed me how. I didn't know how to do laundry either until a friend showed me. I had no idea how to make coffee. Dh has taught me how to change a tire and use a drill (with various bits), band saw, chainsaw, soldering iron, lawnmower, riding mower, edge trimmer, snowblower and a million other tools and gadgets. I would not have known that you have to squeeze the handles together on the lawnmower if dh hadn't showed me. Not everyone knows how to do everything. They need people to show them. Kind of like kids. Dh is very good at grocery shopping, though.
