The most regrettable thing in this life is not to buy a mobile phone for grandma

Grandma was 100 years old a month ago, and I asked Grandma what kind of gift she wanted, and Grandma said, "I want a cell phone, and I can call you when I'm fine." I said yes as soon as I took a bite. I said, "Well, I'll buy it for you next time I'll come back."

I left my grandmother's house and went on like usual, and one week later, I received a call from my aunt who said, "Come back and see your grandmother for the last time, your grandmother is dying, she fell out of bed, bleeding from the ground." Call 120 The doctor said there was no need to send to the hospital, and the old man could not pass tonight. After I heard the phone, I burst into tears in an instant, and when I took the taxi, the tears couldn't stop flowing, and when I arrived, Grandma couldn't speak anymore, I walked to Grandma's bed, and I said, "Grandma, I'm here, did you hear me talk?" Grandma didn't have any response, I just guarded her like this, until nine thirty, Grandma's breathing suddenly accelerated, a few minutes later, with no breathing, my dad fell to his knees, all the people cried in an instant, all knelt on the ground, Grandma has gone, Grandma just left, done all the aftermath, came home, every time I passed by the mobile phone store, I would remember, my grandma said, want a mobile phone. This is the biggest regret of my life! If time could get me through, I would definitely let her old man use her phone once [tears].

Have you ever had such regrets？
