I feel regret 😔😔

The time that I feel regret was the worse. It was one Sunday when we went to my grandma house  and my mom and I were playing Nintendo 64 " which was the best console " but when we were playing my uncle had came form his room and I told him do want to play with me. He told me  going no because he was going somewhere but I didn't care that he was going somewhere because I knew that he was going to be okay but I was wrong. When it was the next day I was in school and then had called down to the office and I see my mom there and I'm like okay what are you doing here. She wanted to talk to me about something in my home, when we finally got home and got inside she started crying and I wonder why is she crying.
Then she told me that my uncle had past away and I couldn't believe it or develop that he had past. So I said that she was lying but when I see her crying nothing is a game so I stared crying. So from that day I regret to give my uncle a hug, a smile, and should had tell him to stay and not leave please. From that I learned to always care about my family and give them all my love and not let another person in my family past.
