Why do I always have to be so smart?

So I think I've done a pretty good job of fixing things around here. You'd think a brand new house wouldn't need much fixin' but gee whiz.
It all started with the dryer. How in the world was I going to make my three pronged plug fit in the mis-shapen four pronged plug and how many times would I try before realizing it really wasn't even the same shape? So Boo took the cord off the dryer, drew up a diagram of the outlet and told me to take it to HomeDepot and ask them to come up with a solution for me. So me being the smart shopper that I am with unattached dryer cord in hand asked the greeter where I would find such tools. He directed me to a general electrical section where I once again tried to match my plug with a new outlet switch because clearly someone had installed the wrong thing. I noticed that the HD was selling new cords. Well clearly I wasn't the only person with this problem because why would they mass produce something like this and sell it here. But it was different enough that I didn't feel confident in mine or Boo's skills to reattach this new thing to our dryer. I asked a couple more people who made it quite clear as to why the other guy was demoted to greeter and one of my fellow smarties explained in detail what I should do. Leaving the HD quite confident, I called two electrical experts that I know and asked them and got the same answers. When I got home I had to use some of my expert drill skills to get a bolt off the dryer, attach the new cord and then call expert #1 as I pushed the button to see if it worked just in case I got shocked and he would have to be the one to notify the authorities that I had indeed failed at the task. Luckily I was victorious.
