I am at college, but every weekend I go home and visit my family. This weekend, everyone else in my family was sick. My brother was just getting over it, my father was still sick, and my mom was just coming down with it. Thankfully "it" is just a really nasty cold.
I was extra careful to wash my hands, tried not to let them breathe on me, avoided their dirty tissues, made sure I didn't eat or drink after them, and just generally was careful about hygiene. I figured that since I was careful, I probably wouldn't get it. If I did happen to get it, it would suck, but it wouldn't be the end of the world. I still went about and enjoyed my day, I helped look after them a bit, and I didn't spend all my time thinking "OMG! They are sick!" Now, admittedly, there was nothing wrong with their stomachs or it would have been a different story.
On Sunday, I had a realization. THIS is the way that I want to feel when someone around me has some stomach issue, be it contagious or not. I want to be extra careful and take steps to make sure that I don't get it, but not freak out it so much that the stress lowers my immune system, prevents me from enjoying my day, and keeps me up at all hours of the night. I want to be able to help the person who isn't feeling well instead of screaming at them, which is the most unhelpful thing you can do.
THAT is my goal, be careful to avoid infection, but not go to extremes.
