My grandma couldn't even recognize me anymore before I left

Dementia. She didn't even stand up to send me off. I went to Beijing. 

Then she passed away. I didn't know it would come so fast.

It's been 25 years.  The grief, of course, is long gone.

Time is the best remedy. No one keeps feeling sad after decades.

Life moves on generations after generations. 

We are all survivors of the past memories.
