First of all, remember that this is just a virus. Nothing dangerous is happening. People do get sick, but they also recover. Norovirus is gross but it's also extremely short lived. By now I'm sure his v*ing has decreased and he'll be back to normal really soon. It really is unlikely that you caught anything. People aren't contagious until they begin to show symptoms, so unless you helped clean up the v* (I know you didn't! ), there was NO WAY for you to have caught anything. You're with your Grandparents (how lovely!)where everything is clean and safe. There's absolutely NO REASON for you to avoid eating or to question what you eat there. You are totally, 100% safe. Get off of the computer and help your grandmother in the kitchen, play a game, ask them if they want to go for a walk. Enjoy your time with THEM! Forget about v*. Not only is it NOT GOING TO HAPPEN to you, it's not worth your time or focus. Id' do anything (include spending a day v*ing) to spend more time with my Grandparents who are all deceased. Cherish this time. Forget about a silly little bug that your brother has. (((HUGS)))
