I cried today

I talked to my grandmother 0n the phone today. She couldn't hear me because her hearing aid wasn't working and told me she was in pain. My grandmother raised us. I thought about how she took care of me when I was small and thought there is n0thing I can do now to make her feel better. She told me she wish she could eat steak so I sent her some. I really cried after this. I don't usually cry. I am not sure why.
