Grocery stores, Walmart and other big stores are packed full of folks older than me who are inconsiderate and oblivious. Getting older has diminished my patience and tolerance for that nonsense. But as some people get older, they lose any consideration for others around them that they may have had when they were younger.You are definitely not alone. I feel much the same way. I don't know if it is old age, or a been-there-done-that attitude. IMHO with the old age comes a lack of patience, especially with other peoples' stupidity. We used to attend a lot of crowded events, concerts, sporting events, movies, theatre. Now we don't go anywhere,and have no desire to go. I don't want to fight the crowds or the traffic, or the parking. I don't want to spend the money on things of very marginal interest.
