I lied that my son had chicken pox
I hope you are joking about that. Why would you lie about your son having a disease?
Because I worried the babysitter will not want to work for me if she's worried about catching chicken pox.
You should not lie about something like that! That could really effect their health! Honesty is the best policy!
I don't care.
You should care about how others feel. It is wrong to lie about something will full knowledge that it is a lie. You don't want to compromise someone's health that it could give that to others too.
