Sometimes my father can be a little bit too set in his ways. He gets stuck with one way of do something until a better way is forced upon him. There have been a number of times where my mother or I have had to just change something and force him to get used to it. He always acts annoyed at first, but usually realizes the change was worthwhile.
For instance, I started to notice that he was always going out and buying more motor oil for his boat, which seemed like a waste of time. I chose to buy him a Mercury oil 55 gallon drum so he was always well stocked and wouldn’t have to keep going out to get more before hitting the water. He was hesitant at first, but now he continues to buy bulk oil in barrels.
