What makes a diary entry different from a story. A diary is written to yourself, at night, about a day that has just ended. So it is written in the first person and the past tense, it may admit things you would not tell others, and it reflects rather than merely reports. Keep the date, day and time on top, and end with a thought rather than an event.

Dear Diary,
Today, I feel, was a special day — not because anything big happened, but because of ten minutes near the Sector 12 bus stop.
I was coming back from cricket practice at about half past five. There was an old gentleman standing at the edge of the road with a walking stick in one hand and two full cloth bags in the other. The evening traffic was heavy and nobody was slowing down for him. He had been standing there long enough for the vegetable seller to notice, because she called out to him to be careful.
I put my bat down beside the vegetable cart, took one bag from him, and asked whether I could walk with him. We waited for a gap and crossed together. He walked far more slowly than I expected, and halfway across I understood how frightening a road must be when you cannot hurry. I carried the bag up to his gate, which was two lanes away.
He did not say very much. He asked my name and which school I went to, and then he said, “God bless you, beta,” and stood at his gate until I had turned the corner. That was somehow better than a long thank you.
While I was crossing I was actually nervous — I kept watching the scooters. Afterwards I felt quiet and glad. I did not tell anyone at home, and I still feel good about it, which I think means the good feeling was not about being praised.
I would do this again, and not only because he needed help. My own grandfather walks with a stick in Ranchi, and I am not there. I hope some boy on that road does for him what I did today.
Goodnight,
Aarav
