@Dap,
I'm usually around the infected people who also have that cold But still haven't caught it without considerably wrenching;
The last 3 words left over from earlier posting yet seemed to fit somehow
while a few days ago when my sister also had a really bad cold and walking around me all the time, still I wasn't infected. Not only then but also a few months ago when my whole family had caught a bad one, and though I was with them the whole time, still Unaffected
