There are some things that I've noticed about Shawn and Gus that just make me smile.
I noticed that Shawn and Gus really have no problem with "swapping spit" for lack of a better way of putting it.
Shawn sipped Gus' coffee without hesitation 9 lives
Gus had no problem taking a drink of Shawn's smoothie. Woman seeking dead husband
Shawn had no problem finishing Gus' cereal even given that it was the same milk Gus had been eating cereal with and using the same spoon Gus had just been using. 9 lives
Those are the only examples I can think of. But you know that it takes a real friend to be willing to eat and/or drink after you. Really, the only way they could possibly be closer is if they were actually a gay couple. At least that's my opinion. lol.
I'd love to hear other thoughts on this subject.
