It does sometimes seem like the hospital staff is more on edge during the night for some reason--at least that's been my experience.

Doctors & nurses can be dicks and just because they help people that doesn't exclude them from being horrible human beings like some of humanity too.

It is annoying and disheartening but try not to pay any mind to their bad mood. They probably had to deal with some nasty people during their shift & were taking it out on you. 

Anyways, I hope your strep throat doesn't take too long to heal. That fuckin' blows. 

Take care & rest.

Don't worry about the delay Josh, tis fine. ^^
