I took the gent I was working with to urgent care yesterday, and I saw people there with so many ailments that were not at all serious, it was a farce. Every single person that answered the question "what are you here for?" said something that made me reply in my head, "What are you doing here"? Drink a lot of fluids, get some rest, and take something that works for you. It's a cold, they aren't serious.
