I had to care for my younger brother last week while he was sick. I tried my best to make him as comfortable as possible.

That's nice that you helped him. I'm sure he appreciated it!

He did, he is nice and well now. I just know how horrible it is to be sick, it helps to have someone to care for you.

Yes, it really does. I am sure if you get sick, he will remember and do the same for you!
