D-daughter M-mommy
D："Mommy，are you leaving home again？"
M："Yes，honey．Mommy is going to fight a monster!"
D："A monster？Is it scarier than a big roaring tiger？Oh my!"
M："Well…yes!A lot scarier!It's called Virus．Many people are working hard to defeat the monster．"
D："Who are they？"
M："They're the scientists who are working on new medicines to cure the ill and the construction workers who are building new hospitals for patients as fast as possible．They are the delivery people who are delivering masks to everyone in need，risking being caught by the virus monsters，too…They are all ordinary people，including volunteers，but now they are also powerful soldiers；they are the bravest fighters and they are heroes!"
D："They are so brave!But mommy，are you scared？"
M："Yes，everyone is scared．Mommy's too．But if no one goes to fight the monster，there will be more monsters，and the monsters will be even more aggressive，and they may defeat us all．"
D："But mommy…I don't want you to leave me．"
M："Baby，mommy doesn't want to leave you either．Sweetie，do you know what "to be brave" means？To be brave is to do the right thing even if you are really scared．"
D："Mommy，I'll be brave，too．I want to be a doctor when I grow up，and I will fight the monsters together with you．"
