Dad's memory is like a steel trap

My theory is that years of raising kids can take a toll on ones health and memory. It was an exciting day, a day of shopping at Sam’s. As usually when you go in they ask for your card. Being the dedicated shopper I always have my card on top so as not to hold up the line. I send the wife and kids over to the snack bar while I did the shopping. It is amazing the more people you take the higher the bill. I had my shopping list of cheese and another $300 of spontaneous got to have its and head for the checkout. I open my wallet to present my card and nothing. I panic as I am slapping all my pockets trying to find it. I am starting to get looks from people in line. Cashier makes announcement for lost card but nothing. I have to head over to the customer service to get a new card. 20 min later I have my new card and I am back in line. Just then the lovely wife saddles up next to me and says, “Here is your card back” I asked in disbelief where in the hell did you get that from. From you honey, you handed it me. I might have as well handed her a $100 bill, no recollection of doing it or why I did it. Sigh. Crap where are my keys?
