I think I'm gonna have my family go home because my son tested positive for the flu.
I'm sorry to hear he's got the flu!  What're you going to do about it?
I will be more sensitive to his needs
I think that's very responsible of you!  Taking care of your family members when they're sick is very important.  I hope he gets better!
I'm concerned that my son will pass the flu on to other people. How can I prevent that?
It's great that you're being so thoughtful about spreading sickness. The best thing you can do is follow your doctor's orders and keep your son away from other people while he's contagious. This will give him space to recover and keep the rest of your family safe.
