As kids we are always amazed at what our mom can remember. Birth weight, exact time of birth, everyone's birthdays, who has what homework to do, who wears what size clothes and shoes, favorite colors, all that stuff. But then we laugh at them when they can't find their keys.
I now know why they can't remember the easy stuff.
You never know when the battery on your car is going to go out and now you need a code to make your radio work again. Where is the card with the code on it? Never mind that we have moved since then and it has almost been 4 years, I should know where it is.
My brother is fixing some plumbing things at our house. He needs to turn the main valve off. It isn't budging, he has tried two different keys. I have to remember if we have ever managed to use that valve and did it work like it was supposed to. The answer, yes, it works, we used it this summer.
You never know when someone will ask you a crazy question and expect you to recall all the details. My keys, my purse, my phone, the kids can look real fast and find them. Or thankfully with phones you can just call it. Easy to fix. The other stuff not so much, so that is what we try to fill our brains with.
Did I ever mention we did finally find Henry's karate picture from last year, we now have this years too!
