“Maowi's current health issue and financial need reminds me of Yeye's story somehow.  If we didn't save for the rainy days, Maowi might not be able to get the radioactive treatment.  So I understand Yeye's feelings and desperation fully now, and only now.  Having savings is so important as you never know the unknown.  ”
