Please be strong for her in her closing moments.
89 years! What a long life! Many of us won't be so lucky to live such a long, full life as she has done. In Japan people who reach 88 used to be paraded throughout their village and honored on their 88th birthday. Even today they receive a special celebration from their family and sometimes even their community.
Please keep her alive by preserving the happy memories you have with her in your heart.
