He said "I Have Been ASKING My Grandson to HELP ME for Three Months Now"

While doing a job for a Client, I noticed an overgrown yard in front of a house that was on the same street after I finished the job I decided to go in and ring the doorbell to see if the Homeowner needed help. The door was opened to me by an elderly man with a cane, then I asked if I could help him in the yard?
The owner of the house told me that he can't do this kind of work himself and he used to have his grandson help him, but for three months now he can't get him to help because he's always busy and he was planning to hire a gardener for the job! He asked me how much it would cost him, to which I replied that I would do the job for free.
The next day I went back and got to work.
I proceeded to remove the weeds from the sidewalk, then cleaned the parking lot near the garage of moss using the nylon brush attachment on the trimmer, but before that I had to collect the leaves. I continued working with the trimmer and went to the backyard, among the thick and tall grass, everything was covered with old firewood and boards, the homeowner told me that I could just mow the area, as he still hoped that his grandson would come and remove all the firewood, but I realized that this would not work, as the firewood was everywhere and also obviously not one year old, so I decided to put them closer to the fence in one pile. It took me about an hour to collect all the firewood, then I went to the front yard and uprooted the dried boxwood bush and took a break, then I started mowing the front yard lawn, first I did it without the grass catcher, just shredded the grass, then collected it in my green bags and then I mowed it again with the grass catcher, in the back yard I just shredded it with the lawnmower and collected it in the bags, but I didn't mow it again.
I then started trimming the shrubbery in front of the house and the hedge, I also had to work hard to trim the laurel tree growing near the house as it was very tall, then I removed the broken wooden section of the fence as it was rotten and already broken. To finish the job, I cleared the garden path where the firewood used to lie.
I wanted to trim the bushes all around the yard, but the owner preferred to leave it as is because he wanted privacy.
The whole job took me 8 hours and a full trailer.
Even though I said I would do it for free, the owner still gave me money and insisted I take it.
