I was in a store the other day. The pharmacy to be exact. Where two older gentleman (older than me, thank you) and myself were waiting for our prescriptions to be filled. The people behind the counter were all young and new. They expended more energy talking to each other in constant stream of information about who is dating who and what party is coming up than in counting the pills. Which I think is rather scary. But, that's not my point.
My point is that I was standing there telling myself "They're young. Be patient. Don't be such an old codger" and yet the two gentlemen and myself were getting visibly irritated. This pharmacy has never taken this long to fill prescriptions, not even with this many people in the store. So there I was diligently attempting to be gracious (well, we'll say shifting from foot to foot, staring at the floor so I wouldn't be glaring straight in someone's face) and it dawned on me, we get to a certain age and everyone behind counters offering us 'service' is younger than us. I think this may be a considerable factor in the old age developed cantankerousness. Think about it. No, think harder.
If I had lived 65 or 75 years and seen so many things, I really don't want a twenty year old talking to me like I'm a child, and I sure as hell don't want someone with not so much, ok no life experience controlling my health/welfare/happiness/purchases/etc. Would you? All the time? Imagine the indignity of having to give up driving and then being condescended to by youngins. It gets my dander up just thinking about it.
So, the next time you meet a cantankerous old woman or man, smile and remember you're going to have to deal with whippersnappers like yourself someday.
