This doesn't make sense

Mark lived in a village far from everything. He lived with his grandpa. Grandpa Vick used to tell mark many stories and old tales but mark was fond of one story, about the hidden treasure which contains gold coins from the Mejia era. Mark remembers every bit of the story vividly in his mind, even though it has been a few years since grandpa last told him about it.

One day when Mark was bored and didn’t have anything better to do, so he went to his grandpa’s room to get some money for no particular reasons. As he was fiddling looking for money or anything valuable he came upon an old wooden box under grandpa’s bed, He took it and opened it. He found that there was a map and a gold coin in it. He read the map, it wrote “gold coins”. Suddenly as Mark was looking through the map, there was sound of footsteps leading towards the room Mark was in. Grandpa Vick had come into the room and found Mark holding the wooden box and the map in his hands, which didn’t belong to him. Grandpa’s expression was cool and there was no sign of him being mad. He said to Mark, “it’s about time u found that and I guess I don’t have much time left, let me tell you about the treasure”. Grandpa then continued, “Remember the story I used to tell about? The hidden treasure one?” Mark nodded and said “yes, I do”. Grandpa then said, “Well almost every bit of it is true and the proof is the gold coin and I want you to have it”.

So listening to the old man explaining about the coin and the hidden treasure, Mark listened attentively and was feeling surprised, confused and sleepy, why not. After that Mark went to his room of what to do next, he began to think of the things that he needed and started to plan and strategize. While he was doing that, he started fantasizing about how his life would change and the life that he would lead and many other fascinating things that one could fantasize about. By the time he woke up from his day dreaming. Thoughts starting to linger in his mind, “what if I go through all these trouble and fail to find the treasure”. Then a second thought “there’s nothing wrong in trying”. He agreed more to the second one. He was listening to Damien rice- “the blower’s daughter” a song that he rather listened at that time instead of Morrissey- “I have forgiven Jesus” it seemed to depressive at that moment.

After sometime, Mark finally made his mind up and was satisfied with the decision he made. He talked to himself again, “fuck that, it’s just a stupid dream and even if I find the treasure, ill just lose my grounds and living rich doesn’t necessarily mean’s living happy”. A voice in his mind said, “Yea right, that’s what all the jealous poor people say”. He stood up, took a deep breath looked at the gold coin which was laying in the box on the desk. He decided to go for a walk and after a while returned home with a smirk on his face. Mark went straight to his grandpa’s room and gave the old man a few hundred bucks. Grandpa asked “what the hell is this and where did you get it from?” Mark replied, “I’ve decided that it was too much hassle and uncertainties which I don’t like and to be looking for the stupid treasure it just doesn’t make sense, so I exchanged the gold coin for credit”. Grandpa looked awed and looked like he wanted to say something but didn’t. Mark added, “My hands are getting tired and so is my eyes, I’ve to go.
