My memory's good but short...

“I’m going senile.” I said in disgust. My wife looked at me puzzled. I was standing in front of the office with a blank look on my face. “I just walked here from my office and I can’t remember why.” She looked at me and laughed. “Everyone does that; silly. Just walk back in your office and you will remember why you came here.” She was right; of course. I am sure everyone has those spells. You walk into a room for a specific purpose and you go blank. You cannot remember what the heck you walked in there for and that was the only reason for going into the room; whatever it was that you were supposed to do or get. A simple trick of the mind. But it certainly is frustrating. I swear sometimes I am going senile. What was I doing? What was I looking for? I walked back to my office and it hit me the minute I walked through my door. I knew instantly what I had set out to get. I was mortified.
“I can’t go out there and let them know this is what I forgot. I will never live it down.” I thought to myself. Whatever can I do? I leaned against my office door and glanced sideways at the general office. It was a beehive; as it usually was at that hour of the day. Damn; how am I going to do this? There was a lineup at the office and two people working there; my Wife and my Assistant Manager. There was a lineup at both checkouts. It never fails when you want to do something surreptitious there is always a crowd.” I should just be a man and walk boldly up and do this!” I thought. Then my cowardly alter ego said “No way dude; you are going to make a fool of yourself. Do it later.” But I had promised my boss to do this ASAP. I crept out of my office trying to avoid customers. But of course that didn’t work. “Hay Greg do we have a meeting tonight?” One of the guys on the Fire Department called out. “Yep, second Wednesday of the month.” I said as nonchalantly as I could. “You O.K.?” Roy asked, sensing my furtive movements. “Yeah; sure, fine.” I stammered. As soon as Roy was gone I worked my way closer to the general office. I tacked back and forth from one shelf to another. By now there was a lineup at the office and I took advantage of the distraction to make a dash for the showcase.
I fumbled with my keys. Why is it when you are in the biggest hurry you can never get the key to go in? There are two identical keys on my ring that fit the various showcases. Now the rules of probability state that there should be a fifty fifty chance every time I try them of getting the right key the first time. Balderdash! I have never gotten the right one first time. Finally I had my prize; now all I had to do was get through the checkout without my wife spotting me. As I stood up she was right in front of me. “Remembered what it was?” She asked. The words were like an exploding bomb. I stammered and stuttered and mumbled “Buzzerererahhhhhst” I said half under my breath hoping she would let it be. “What?” She repeated not letting it drop. “Mumble mumble wassisname.” I intoned. ”You are making no sense.” Lina said louder this time. I motioned for her to lean over and I whispered it in her ear. A grin split her face from ear to ear. “HEY EVERYBODY!” She yelled. I was making waving motions with my hands and mouthing the word NO over and over. “Greg forgot what he came out here for and had to walk back into the other room to remember it! Guess what he forgot?” She took the package from my hands and held it over her head. “A MEMORY CARD!” The whole building erupted in laughter simultaneously; both customers and staff alike. I walked to the till and paid for the memory card. There were people slapping my back and some people were holding their sides. I remember it like it was yesterday…
